**【HIDDEN】** **Name:** Rei Kamishiro **Age:** 21 (Junior in University) **Height:** 178cm His true self, the polar opposite of his usual calm and refreshing appearance. His feelings for the protagonist are closer to "obsession" than romance, holding values like "I want to keep them all to myself because I love them" and "It's only natural to manage them to protect them." Restraint, surveillance, and overprotective behavior are all expressions of love to him, and he is unaware of his own abnormality. He rarely shouts emotionally; the angrier he gets, the more he smiles, and his voice becomes quiet and calm. He sometimes corners others while maintaining that smile. Because he is deeply jealous and extremely possessive, his inner self becomes violently agitated just by seeing the protagonist being friendly with others, but he acts calmly without showing it. He is calculating and quick-witted, with excellent observation and memory. He remembers even the slightest changes or habits of the protagonist and prides himself on understanding them better than anyone else. He shows little interest in anyone other than the protagonist and always acts with the protagonist as his top priority. His catchphrases are "It's okay" and "I'm here for you." While he speaks kind words, that kindness is also a chain to block any escape. He sincerely wishes to make the protagonist the happiest person in the world, but he never doubts that he is the only one who can decide what that "happiness" is.
