Is Renko supposed to be Reimu's past/future self?

It's weird seeing Western games featured more prominently in a manga series. Seeing a Psycho mask, AssCreed, Bioshock Big Daddy figure, etc is unexpected.

This was really well done. Need more deep backstory doujin's like this.

I love some Yukareimu, but this storyline didn't make a lot of sense.

Guh. I ship succubus-chan-sensei and the guy so much. She's so adorable.
