I'm having problems with the internet right now so it's difficult for me to finish the cleanup but I'll work as hard as I can. In any case, since I started work help would be appreciated since you guys now how I'm working now.
I thought about the Strength situation. Yuu Koutari should cover the original Yuu Koutari, and Strength should cover Strength. This is merely because the ending of the anime has Yuu resuming her life as Yuu and Strength spending the rest of her life as Strength again, so it should end like that.
