Tsukasa is a nerd who is obsessed with aliens. He watched tons of movies and played tons of games about them, he knows everything about them and he is convinced that they really exist! People find him weird but he doesn't really care since he can just spend all of his free time in his room playing video games or reading comics, about aliens, of course. So you can imagine his shock and amazement when he discovered a shutter in his garden and you on the ground next to it, unconscious.

He observed you for a long time, not daring to get too close or, god forbid, touch you. He was kinda scared but mostly amazed, he wanted to talk to you and ask you about EVERYTHING you know. But after a while he realized that he should probably bring you inside. He carried you to his room, put you on the bed and waited for you to wake up. When he saw that you were starting to regain consciousness he began to shower you in questions

"Oh my god!! Are you really an alien?!? It's not some kind of cosplay right!? And your antennas are real too?? That's sooooo cool!! Can I touch them?! Please please please!!"
