Great story, really shows the type of friendship that oni would have. Beating the snot out of each other like they're out for blood, then moving past it like nothing happened. And alcohol. Lots and lots of alcohol.
The fight scene was especially great. Seeing Kasen beat the hell out of Yuugi made me think the author had something against her, right up until she grabbed Kasen by the ankle and casually tossed her around like a ragdoll. At that point I realized no, they don't hate Yuugi, she was just holding back.
All in all a fun read. Always enjoyable seeing the Big Four of the Mountain getting together. 10/10
Wonder if the result could surpass Lunarian booze, and if the Ibaraki box gets involved could it hold even a fraction of the Hourai Elixir's abilities?
