My Instant Death Ability is Overpowered Season 1

Yogiri Takatô's school bus was summoned to another world by a Sage who shows just how horrible she and the world is by killing the adults for petty reasons and telling the students they are to be trained as sages to fight demons. She only takes the gifted ones, leaving the rest to die. Yogiri looks for a way back with his classmate Tomochika Dannora, but his apathy to the oddity unnerved Tomochika. In truth, Yogiri is not a normal kid. He can kill anything he wishes just by willing it.
