Hibiki Volume 12.
So Asumu falls into the basement of Tachibana, where they develop disc animals and tools as well as store other items (Like the classic disk animals, which were cute origami scrolls). It's pretty cool. There he meets with Midori again, and she teaches him about the oni and Hibiki. It's rather nice to learn about Hibiki, seeing that he went through similar problems in middle school such as helplessness. It helped Hibiki strive to become an oni. We also learn that Makamou can only be defeated by pure sound. Alrighty~
There's also a brief scene where we learn that Akira also attends Jounan, the same school as Asumu and...Girl (Goddammit). That's neat, though not super interesting, honestly. We'll see.

All during this, Hibiki is working on defeating the tree monsters and the Makamou, which is apparently a giant snail with a tree for a shell (And tentacles. Of course). He soon learns that their power boost is only available to them in limited bursts, so during their next encounter, he chooses to dodge and fight defensively as he waits them out, using a large legion of bird and wolf disc animals to help him out. Eventually it pays off and he defeats them once their power wears off. Next is the rampaging Makamou, headed for a village. He doesn't pose much threat, considering it's a flipping snail. Hibiki destroys it with little effort.

I rather liked this episode. It gave me something I really wanted, history on Hibiki, as well as actually helped move Asumu into the circle of characters who knows what's going on (As I was getting weary of how distant Asumu and Hibiki's stories were starting to move). While it wasn't the most in depth or dramatic episode (This episode was more action heavy than typical), finally learning a little about Hibiki as well as getting Asumu out of his depressive funk (For however brief) was nice. Asumu hearing of Hibiki's feelings of helplessness as a friend transferred schools due to a fight while around the same age as him and growing past it helping Asumu put the shoplifting incident behind him was good.
