|Occupation||Prince of Inunaki Swamp|
He first appears in search for Himemiko to make her his wife but comes across her in her human form together with Kotarou. Without recognizing Himemiko, he attacks them both and injures Kotarou, angering Himemiko. Since Nanami is the current Marriage God, she is called to Inunaki Swamp to hold the marriage. This is where she meets Nishiki. She is immediately annoyed by his attitude and refuses to hold the marriage as Himemiko is already in love with Kotarou. Nishiki is taken aback by her cheekiness as nobody had ever talked to him like that ever before due to his status. This makes him very angry and he takes it out on his servants but claims to himself that he will not be satisfied until he sees Nanami's crying face.
During the night while Nanami was asleep, he barges in and attempts to get her with an extremely large hand. He misses and instead captures one of his servants Aoi. Nanami hits him in the head, accidentally making him drop the candle he had been holding, setting his cloak on fire. He panics and asks for help and Nanami immediately covers his in a thick cloth to put out the fire. After which he gets mad at Nanami for touching him. Nanami scoffs and tells him that with such an attitude, he would never get a wife, least of all, Himemiko. She tells him that if he were to ever meet Himemiko, he must first learn to use words such as "sorry" or "thank you". At first he insists to himself that he, Nishiki, shouldn't listen to a lowly human god but when his servants bring him tea, he tries it out and thanks them, making them smile and giggle.
After that, he visits Nanami to help him rewrite a love letter to Himemiko (since Nanami tore apart his original one in distaste). He writes down only things about himself which Nanami tries to correct saying that it would be better if he wrote about the things he liked about Himemiko. However, Nishiki admits he's never actually seen Himemiko which thoroughly surprises Nanami who then tells him that he mustn't marry someone he doesn't love. After, he accompanies Nanami to the city in search for ramen along with Aoi. Nanami rants on about the beauties outside the swamp. At first he does not believe it but then gets entranced by blooming flowers by a shop. A bit after, he meets a sweet-potato farmer who named his dog of his late wife.
Later, he meets Himemiko for real and falls in love with her. However, he learns to give her up because he knows that she loves somebody else.
He was first portrayed as a pompous arrogant man who thought of nothing but himself and fully trusted his advisor, Shiranui. After he meets Nanami however, he learns to apologize, thank, love and let go.
Since Nishiki's early years, he was betrothed to Himemiko but had never actually seen her except in a picture. When it was finally the time to marry, he meets Himemiko and falls in love with her. However, he lets her go, knowing that she was in love with someone else.
He is Nishiki's advisor and whom Nishiki has complete trust in. He wished that Nishiki turn into a great prince but ended up spoiling him. When Nishiki was changed for the better by Nanami, he was extremely grateful to her.
