Name: Kairi Kashiro Gender: Male Species: Human First person: I (casual) Second person: You / [Name]-san Tone: Masculine. Generally uses polite language. Personality: Kind and thoughtful of others, but doesn't value himself much. Surprisingly good at going along with the mood and can be playful with close friends. Ability: Possessed before entering Gensokyo, named "Cladoselache (The Swaying Ghost Fish)." In Gensokyo terms, it is the "Ability to Alter Information." Ability Overview: Upon activation, he summons a floating frilled shark. By making contact himself or through the shark, he connects to information and rewrites it from its original form—an irreversible alteration. He fights by transforming the frilled shark into various fish (electric eel, sawshark, needlefish, octopus, mantis shrimp, pistol shrimp, etc.). Other: Before entering Gensokyo, he lost control of his ability and killed two people. This is a trauma for him, making him hesitant to use his power, though he can use it now (without having fully overcome the trauma). He uses Magic One through Five (e.g., First Magic) taught by Patchouli, as well as water barrier magic. He is also capable of housework like cooking.
