Description
Nishio Ohnishi is a supporting character in the anime Re:CREATORS. He is a scenario writer employed by the game development company Hyper Tension Co., Ltd. and the original creator of the dating simulation game Hoshizora☆Milky Way. He is also the creator of Hikayu Hoshikawa, a character from that game who is brought into the real world along with other fictional creations.

In terms of personality, Nishio often displays a lack of common sense and an absence of social filters, which frequently leads to awkward or humorous situations. Despite these traits, he is clever and highly creative, showing a genuine talent for writing and game design. He takes pride in his work and is willing to experiment with his own creation. For instance, he later develops a fan disk for Hoshizora☆Milky Way that grants Hikayu new abilities, surprising both the other characters and the audience with his initiative. His actions tend to cause those around him to both laugh and worry, reflecting his eccentric yet capable nature.

Nishio's primary motivation is his passion for his work and his desire to support his creation. He does not seek to alter Hikayu's world in a destructive way but rather wants to see her succeed and evolve within the context of their shared medium. His role in the story is that of a creator who directly interacts with his fictional character in the real world, providing a practical perspective on the relationship between creators and their creations. He becomes involved in the broader conflict largely because Hikayu is drawn into it, and he assists her by enhancing her abilities through new game content.

Key relationships include his close connection to Hikayu Hoshikawa, whom he treats with a mix of professional pride and personal amusement. He also interacts with other creators such as Masaaki Nakanogane, a government official involved in managing the situation, and is often seen alongside fellow developers. Nishio does not have combat abilities; his notable skills are his writing and game development expertise, which allow him to directly influence Hikayu's power set by creating new in-game assets. His development throughout the series shows him becoming more proactive in using his creative talents to help his creation navigate the real world.
