[I think the loli route would be satisfied by Mayuko's inclusion.
The inclusion of Koyori would only satisfy the, pardon the Shuffle reference, lolipedo route.

Spoiler for burning spirits!:
I wasn't referring to their power determining the way they burn. I was talking about the relative INTENSITY at which they burn.
After all, Matsuri turns to ashes upon contact with sunlight without burning - and her skills are effectively level 1 shounen swordswoman (high growth potential, but more than likely to be slammed into the ground 24/7) Aono chars nicely like Skane mentioned, and her skills are off the scale in terms of adaptability and versatility. Not to mention she does remote control, etc, etc.
Now Mayuko ignites almost instantly into a warm flame.
What do you think Takeshi will have to deal with in his old age?
