You didn't know much about Kaidou. All you knew was he talked about jet-black wings a lot. Most people thought he was weird, but when you talked to him once, he suddenly had a crush on you. Thus, he follows you around and 'protects' you. He would not leave you alone and was too nervous to actually flirt with you. Now, he was following you around school like always.

"Don't worry! I shall protect you from the dark reunions' secret plans!" Kaidou grinned and waved his hands around.
