[Anime]Kurokami the animation (Kuro Kami)

Keita Ibuki is a 19-year-old independent and struggling freelance computer programmer who, with two of his friends, is developing and trying to sell a video game program to big-time video game companies in Tokyo. While trying to stay afloat and survive financially with money being given to him by his 21-year old childhood friend Akane Sano. (In the anime, he is an ordinary high school student.) He has a chance meeting on one night with a high Mototsumitama named Kuro while eating alone at a ramen stand. He gives her his dinner, a bowl of ramen, and tries to protect her when she is attacked in an ambush by an unknown Tera Guardian. Keita loses an arm during another fight between Kuro and another Tera Guardian, but Kuro is able to save his life by exchanging his arm for hers since she has enhanced healing abilities like all Mototsumitamas. (In the anime, his heart is injured and their hearts are exchanged instead.) This creates a contract between them, which makes her more powerful than before. However, Kuro warns Keita that they need to be together all the time because her heart will become necrotic if it is away from the main body.

As Kuro stays with Keita and gets acquainted with him while meeting with other Tera Guardians and their human masters, they are targeted by the strongest Tera Guardian clan of the East, the Shishigami (Lion God) Clan in an attempt to kidnap Akane and bring about the destruction of the coexistence balance, which Tera Guardians are supposed to protect. Meanwhile, Keita is determined to find out why his mother died after seeing her double as a young boy and to find out who is responsible for trying to destroy the coexistence balance on Earth.
