This series seem strangely interesting. I wish I could find the translated novels somewhere (on the optimistic hope they've even been translated by someone. I've seen at least one effort but they're only about halfway through the first,so far.)
This is based on a currently ongoing OVA series. Two episodes have been released so far. Character names : Juuzawa Juu, Satsuki Miya (baseball bat girl), Ochibana Ame (girl that saves guy). (should check it incase I'm mistaken) Maybe a small spoiler for the OVA: This series of pictures actually represents a scene that happens in the 1st OVA
I don't have the time left to do all the tagging so I hope this helps
