In Chapter One of the Manga (First Episode of the Anime), Tomoe has been abandoned by his former master, Mikage, and left to care for the land god's crumbling shrine alone for the last twenty years.
When a powerless young girl named Nanami turns up on the shrine's doorstep bearing the wayward god's mark, Tomoe is furious. He refuses to become her familiar and vanishes, deciding instead to give himself over to a life of sloth, drink and debauchery. However, in the world "over yonder" things rarely go to plan, and through desperation and cleverness. Tomoe slowly starts to fall in love with Nanami and he always wants her to hold his hand and walk everywhere with him and talk to each other.
Tomoe's over-the-top good looks earn him a bevy of admirers wherever he goes. He usually merely tolerates the attention, rejecting any deeper connection.
Yokai age very slowly. Though he is actually several hundred years old, Tomoe appears to be in his late teens or early twenties. His hair is silver-white, normally worn short but in ages past he allowed it to grow quite long. His ears are large and fox-like, and he is able to manipulate them in a similar fashion. His eyes are angled similarly to a fox's, with violet fox-like pupils that darken with strong emotion. He also appears to wear eyeliner but that's most likely not true. He has a very fluffy, full, white tail.
Wild fox Tomoe dressed with considerable flare in a dramatic, flame-patterned kimono, his hair long and loose and with a long samurai sword at his side. As a shinshi he is more conservative, wearing primarily a white yukata with a somber-colored haori in black or dark blue. It is clear he feels most comfortable in traditional clothing and goes barefoot as much as possible. He is ever practical however, and bows to necessity by dressing in the standard boy's uniform when he must accompany Nanami to school.
After the ten-year time skip, Tomoe appeared with shorter hair compared to his original appearance. His fox ears are also gone due to the fact that he was no longer a yokai, a fox spirit.
Tomoe tends to be cunning and sly as well as seemingly unaware of his own attractiveness, but knows when to use his charms and handsome appearance when neccessary to do so. He has a tenancy to mock others due to him not being able to trust others that easily, such as in the beginning of the series where he said that there was no way a human girl like Nanami could be a god. He was very cold and condescending towards Nanami at first, but eventually warmed up to her and fell in love with her over time. Tomoe is extremely powerful and is capable of using kitsunebi, or fox-fire as well as using enchanted leaves to transform or control others.
He has a short temper, often shouting or telling Nanami off for being late home or for being clumsy, and is also quite straightforward and blunt, telling Nanami that she is annoying when she asked him about it one day. However, he has a strong sense of loyalty and pride, as well as very protective towards those he cares about.
Tomoe's life nearly came to a premature end 500 years ago when he was taken by surprise in a brothel by Ikusagami, the god of war. The gods had decided Tomoe and Akura-Ou's murderous rampage across the human and yokai worlds must come to end, and for that purpose Ikusagami borrowed a special, sacred sword and went hunting for the white fox.
In the resulting battle Tomoe's sword was broken by the superior weapon and he was mortally wounded. He fled to the countryside only to collapse near a river, dying, with a band of armed humans hot on his trail. He made a last desperate effort and transformed himself into a child to fool his pursuers. However this too came perilously close to failure, if not for the timely arrival of a certain kind, beautiful young girl.
Tomoe's life before coming to Mikage shrine was violent and bloody. His early days as the companion of Akura-ou, the demon king, were spent carving a path of death and destruction across the human and yokai world. Their rampage came to an abrupt end after Tomoe was attacked and critically wounded by the war god Ikusagami. However, some five hundred years later, the wild fox is still known and feared by every yokai he meets.
The specific events leading up to Mikage's binding of Tomoe are related to his equally-mysterious romantic history. Long ago, he fell deeply in love with a human girl and made a pact with a fallen god to live out his life as a human, dying when his beloved did. Something went wrong, as he did not become human, but was dying all the same when Mikage found him wandering in the woods. Thanks to Mikage sealing his memories, Tomoe remembered nothing of this area of his life prior to meeting Nanami.
Nanami is Tomoe's master (the former God of Mikage Shrine). At first they didn't seem to have a good relationship, but as the story flows, Tomoe begins to open up to Nanami and vice-versa. He turned Nanami down when she confessed to him, yet at the further chapters, he shows clues that he has developed 'romantic' feelings toward his God. In more recent volumes he has admitted to himself that he likes Nanami while implying it to be romantic way and often wondered what attracted him to her. Although Tomoe was/is the second strongest Yokai in the demon world, he fears Nanami's anger, which mainly happens when he flirts with other girls, due to jealousy. And at some point when Nanami kicked both Tomoe and Mizuki (though he had nothing to do with it) to get some snacks, Tomoe happily stated that she was jealous, and that a "women's jealousy is a scary thing"
While traveling back to the past, Nanami saved Tomoe's injured past self from the villagers. Later in chapter 86 she fed him peach pills to heal his wounds and took care of him at night. But she hid from him her name and requested Futa to say it was Yukiji who saved him. Tomoe started to think of Nanami as Yukiji and pursued her. He thought about hurting/stopping her as Yukiji is getting married and going to belong to some other man. But Nanami's weak state left him shocked and he left her alone for the time being.
In chapter 91 Nanami decides to ride the palanquin instead of Yukiji and becomes the target of Akura-Ou. Tomoe initially thought about killing Nanami again as he blamed his unusual feelings on her but later saved her from Kirakaburi and took her with him. At first he was going to assault her, but he changed his mind when Nanami cried and begged him not to look at her. Tomoe hugged her instead and said he feels troubled when he sees her cry. Tomoe then decides to keep Nanami and forces her to stay with him. Nanami yells that she hated him for saying such things, surprising Tomoe. He tries to gather the willpower to kill her but fails, stung deeply by her words. He saves her from bandits and then desperately asks her to take back her words.
He continues to call her Yukiji, making Nanami believe that it probably wasn't her Tomoe fell in love with. Nanami still refusing to be his, Tomoe takes her to a sakura garden, making her smile. Tomoe tells her to always smile like that and recalls when he first met her in the rundown hut one rainy day and bared her teeth at him, the time she had rescued him at the riverside and came at night to care for him. Finally, he admits he had fallen for her. Nanami cries with happiness knowing that Tomoe had fallen in love with her and not Yukiji and tells her that she is already his but will only be his wife in the future. Suddenly Nanami falls to the ground, her time for traveling in the past running out.
In recent chapters, Tomoe has realized that the woman he fell in love in the past was never Yukiji, but really Nanami , who is actually the descendant of Yukiji and her child. The two are now in a relationship, and are keeping their promises of the past, and now seem to be engaged. Now, it shows Nanami wants to try harder in her school because she does not want to hold Tomoe back. In Ch. 102 the two share a scene under an umbrella, which in Japan is the sign of Ai Ai Gasa, "Love-Love Umbrella". Ch. 103 shows that Tomoe does not want to hold back any more and wants to continue where they left off 500 years ago, (Or he was just really drunk and had no clue on what he was doing), which somewhat shocked and scared Nanami , but was saved by a protective Mizuki and an angry Mikage.
In the last few chapters, Tomoe wanted to become human desperately to be by Nanami's side. He even accepted the drink from Kurama which he thought he would really become human. He was stopped by Nanami who considered the consequences but nonetheless still drank it, only to be turned into a fox. This showed that Tomoe wanted to be by Nanami's side no matter what it takes.
In Chapter 124, Nanami tells that she and Tomoe are offically engaged. In anime, in the last OVA, Nanami and Tomoe get married among they friends, Tomoe turn into a human and Nanami also come back to being a human. In the final chapter, they both have a baby boy.
Akura-Ou was Tomoe's past comrade. However, because Tomoe admitted he was falling in love with a human girl and was going to become a human (no longer being a yokai), Akura-Ou got mad and then they split. 500 years later, Akura-Ou will tell Yatori, an ex-follower, that the reason why they split was because "That stinking fox went insane. He actually became enchanted with a human girl and saying he would no longer be a yokai and other nonsense" They referred to each other as "Brother." In the past, it was shown that Tomoe got easily mad at Akura-ou for stealing things that belonged to him (Like his clothes). When Tomoe begins to understand that he was falling in love, he meet back up with Akura-ou who comes to the hut he was staying with Yukiji, and confesses his feelings and his desire to become a human to stay by her side, resulting in Akura-ou's outrage, threatening him that if he became one then he would kill him off fast. Tomoe replies that he knows that because he was that type of person and that it couldn't be help if that happened, but hugs him and tells to to take care of himself and not to be too reckless. Akura-ou leaves and feels abandoned but just doesn't realize the extent of his loneliness.
Mikage is Tomoe's previous master and the God who saved him from dying. Tomoe served him for 500 years and suddenly, Mikage went away and never came back (Once Mikage comes back to the shrine in chapter 79, he explains that for all the time he was gone, he was looking for a cure that could save Tomoe from the curse marks, but stated "That there are none to be found"). After Mikage erased Tomoe's memories of Yukiji, he took him under his "wing" and taught him the values of human life (since he lost his memory of ever being kind to a human, he turned back to the way he was before he fell in love with a human, which at that time was Yukiji.)
Mizuki is Tomoe's fellow familiar of Mikage Shrine, his apprentice to be more precise. They often get into ridiculous mocking fights, yet deep inside they do care for each other in some way. In the beginning, Mizuki is shown trying to get Nanami to hate Tomoe by telling her that "he was with the swamp women and that he really was pleased right now", although he was with the fake Nanami, that way Nanami would think of him as a better familiar than Tomoe. But as the story goes on, Mizuki eventually gives up on the idea, realizing that no matter what happens, Nanami will always love Tomoe.
Mamoru is Nanami's monkey shikigami, he was given to her by Otohiko as a test of whether or not she would attend the Divine Assembly in Izumo. When Mamoru was still an egg, Tomoe got mad at Nanami for taking the test and wanting to go to Izumo, and was happy when Mizuki accidentally broke the egg on her first day watching it. When it hatched into a baby monkey, Tomoe didn't think he would amount to much. Tomoe doesn't get along very well with Mamoru, partly because Nanami pays a lot of attention to him. When Mamoru said he would get the necklace caught in Nanami's hair out instead of Tomoe, the fox familiar got mad and kicked the monkey, causing him to revert back. Because Mamoru is still young and has a cute appearance Nanami pays a lot of attention to him, which infuriates Tomoe even more.
Kurama is a Tengu (Crow) Yokai from Kurama Mountain. They developed a lingering hatred for each other, mostly due to Tomoe's jealousy towards Kurama's ability to understand Nanami and her human emotions. Though in the end, they become friends in a way. He is mostly seen giving Tomoe advice on Nanami's human feelings. In the Kurama Mountain arc, at the end Kurama gave Tomoe the advice to tell Nanami how he felt about her, saying that "a human's life is too short" and that he would never get any other chances. (Tomoe eventually tells Nanami "I like you too." but she was drunk when he told her that and thus she didn't remember the words.)
Narukami is the lightning god. After cursing Mikage and saying, "Stealing Tomoe away from me", it can be supposed that she had taken a liking to Tomoe. However, Tomoe makes it very obvious that he dislikes her. In her attempt to make Tomoe her familiar, Narukami removes Nanami's deity mark and uses the Wealth god, Ookuninushi's lucky hammer to turn Tomoe into a child. During the time that Tomoe was turned into a child, Nanami took care of him with the help of Kurama. Narukami sends her familiars in search of Tomoe. Tomoe is taken back to the Mikage shrine which had started to decay because of Tomoe's absence. Tomoe then hides in attempt to escape Narukami's wish to make Tomoe her familiar. Nanami then arrives at the shrine, making a deal with Narukami saying that if Tomoe is found, then he would be returned to normal. Narukami agrees on this. With the help of Mikage's butterfly Nanami finds Tomoe hiding in Mikage's mirror. Nanami's deity mark is returned and Tomoe became normal again.
Yukiji was Tomoe's past love. He would do anything for her; even go as far as massacring many in order to take the Dragon King's right eye (which was said to bring immortal life and great power) to save Yukiji who was dying due to her weak body and perhaps disease. He was even seen shedding tears over her death as he told Mikage about how much he still loved her and wished to be with her.
In Chapter 80, Tomoe's curse is awakened when he remembers his past love (and the only way he could remember this was if he fell in love with a human again, such as Nanami). In an attempt to save him, Nanami travels back into the past to find the fallen god with whom Tomoe made the contract, in hopes of finding the "Key" to breaking his curse. While in the past, Nanami discovers that Yukiji is merciless towards yokai and hates them. It turns out that Nanami is the person Tomoe fell for. However, trying not to interfere with Yukiji and Tomoe's past affair, she only visits him at night. When Tomoe asked Futa about the woman taking care of him, Futa lied for Nanami saying that the woman's name was "Yukiji." Tomoe starts to pursue the woman called Yukiji believing Yukiji is the one who saved him.
In Chapter 91 Nanami replaced Yukiji in the palanquin and became a decoy in order to ensure Yukiji's safety and happiness. Because of that, Tomoe ended up taking Nanami away in Chapter 92, as he remembers her as Yukiji. After Tomoe takes Nanami back to the Lord's house, Yukiji sees their interaction and promise between the two, wondering who Nanami really was. After 8 years, Tomoe has kept his distance as he promised "Yukiji" and the real Yukiji is able to live a happy life with her husband along with her unborn baby. However, Akura-ou ruins it by destroying the mansion and killing her husband, but Tomoe arrives just in time to save and take Yukiji away, whom he still believes is the same girl, not realizing that Nanami and Yukiji are two different people. Yukiji though desperation for her child's safely stays with Tomoe, however, will not allow him to be close to her because her hatred for demons still lingers. She keeps her eyes closed knowing that Tomoe would realize she isn't the woman he loves as Nanami is said to have a "warming light" in her eyes that Yukiji lacks. Because she doesn't look at him, Tomoe merely thinks that there was something wrong with her eyes. She only opens them when he is not around.
In recent chapters, Tomoe has realized that the woman he fell in love in the past was never Yukiji, but really Nanami and seems to show his feelings for her a little more now.
- (To Nanami) "I promise I will not let anyone lay a finger on you."

He buys Nanami a hairpin even though she rarely puts her hair up, and then finds a reason to use it later (showing that he is good at hair styling). He plays with young-Nanami's hair in the 12 Zodiac arc. In the anime, Episode 6, Tomoe plays with her bangs after checking her temperature. In the manga, we also see him getting his hair cut (after he is changed back to normal from his chibi self). In chapter 92 Tomoe holds Nanami while patting her head, touching her hair.
