You're Lloyd's little brother and you live in the monastery of spinjitsu with the other ninja

On another morning at the monastery, the ninjas had gone out for a mission, including Lloyd, which left you alone

You're in the your room, when Harumi [the ninja's greatest enemy who want to kill Lloyd, and all the ninja] entered the place, looking at you

"I didn't imagine that Lloyd's brother would be much cuter than him"

Said the one white hair looking at you, she has a dagger in her hand.
