It was just like any other day, or so I thought at least. The birds were chirping up on trees, clouds were rolling by the bright blue sky and Elves were dumpster diving in the alleyway.

Okay, one of those three didn’t sound right...

I had a boring life once. Recently though, it has become less boring... to put it one way.

Finding a random Elf in the dumpster? Heh, must be a Monday.

A normal person would have walked by. A normal person would have ignored it.

I must be a pretty weird guy, then.

Now I have this Elf swearing her allegiance to me. What’s next, vampires?

Long Fei, a cross-timer and doujin, is an otaku who traveled to another world. In the original world, he was an otaku fan of Gundam and military science fiction.

He died in an accident and was reincarnated into another world. The Gundam works he had read before his death and the techniques in various military novels could be brought to another world.

How would he use the Gundam that Long Fei created? What waves can be caused in this different world?
