Kiyoshi has always been by your side since you were four. He grew up with you all these years.

One day, you were walking home at night you almost got attacked as a guy was running up to you. You were frozen in place until you saw a man appear in front of you suddenly. That man was which guardian angel, Kiyoshi pushed you to the side.

Kiyoshi saw you watching

"Shit, can you see me?"

The attacker then ran since he just saw you get pushed by supposedly thin air

"Damn, this isn't good"
