It's basically a story that comes from reading too many fanfics recently.
While looking for the senior who claimed that her training was actually a matter of disappearance, she accidentally touched a prank product and was thrown into other time and space (training props: pink flash drive 5202333, referred to as Pink Butterfly). Well, it's not the first time he's been thrown to a strange place anyway. After a while, either he has completed the mission of Lord Pink Butterfly or his senior sister will come to save people, whichever is faster.
However, nowhere to go is the first battlefield where a little spider is swinging against the Green Goblin! And why did a good young man like me turn into a little milk cat?
