I want to just drift through life in Type-Moon.

Reincarnated into the Type-Moon world, I, Yue Zhengling, just want to live a normal life and drift through life. Why does the situation seem more and more wrong?
Ever since I encountered the Twenty-Seventh Ancestor of the Dead Disciples, my life has been plunged into misery! All I want is to be a decent human being!
He learned a couple of sword techniques from the magician of Avalon, honed his martial arts skills at Ryudouji Temple, moved into the Kuonji Temple mansion, was forced to travel around with a little girl, and even participated in the Earth's Glass Burning War! Sounds impressive, right? But what a joke! What's my opinion?
They travel between parallel worlds, forging various connections.
I, Yue Zhengling, am still struggling to survive in various dangerous situations today.
Finally, I decided that once I found my grandfather, I would definitely give him a good beating!
He's so skilled at tricking his grandson! I guess I'm not his real grandson after all!
