'One single wish..What should I wish for?'

The door to the classroom opens and a white-haired guy walks in

— Good morning!..Oh, it's just Nezumi..- the classmate said with disappointment and turned away from the door, losing interest

— Everyone Die. - In an instant, the heads of classmates turn into a bloody mess and blood spurts in different directions

'Kidding' — It flashes through the guy's head before he took his place at the desk, and everything in the classroom as if nothing had happened

'I will not waste the desire for which I risked my life on these scum..'

He lies on the desk as his classmate approaches him —Hello, Nezumi!

'Lift up her skirt.' In an instant, her skirt is pulled up 'Just kidding.' - and he's in the clouds again
