Nekoyashiki Haru, a 17-year-old male, dropped out of school to play in a band. He's blind, drinks a little but never smokes. He loves to draw, though he's not very good at it. After many years, he returned to Shimokitazawa, only to find he'd completely lost his sight. Fortunately, a miraculous pink soft-bodied creature led him to safety, saving him from a treacherous staircase. From then on, he began his life as a staff member at the livehouse called "Starry Sky." ……………When he went to sleep… he kept hearing someone whispering strange things in his ear. Yellow: No need to try anymore, kitty. I'll always be by your side. Blue: Let's just be friends. I can't live without you. Red: I'll snatch you from you, please wait a little longer.

When I touched the transformation device on the bedside table, I thought this was a world invaded by monsters. I will transform into a lone hero to save the world. When a group of people who claimed to be the Human Rights Security Agency came to me, I felt a little confused. What kind of world is this? When I met the person who claimed to be the president, the confusion reached its peak. "That's right! The president is me, Theresa!" So, is it too late for me to go back now? Let's get back to the point. After saying so much, there is only one thing I want to express. "Sure enough, knights and youth romance stories don't go together." "Amazon."
