This is not good. Only read it if like me, you want to read everything related to Crows or Worst.
Its basically a collection of short stories. Only two of them are enjoyable:
The one with the armament is pretty cool
The Hokuto no Ken one is funny because of sheere absurdity, transposing HnK characters into Housen academy
The rest is aweful

The art is pretty good, but nothing to write home about. The story is abysmal
Most chapters are boring (but you read through them very fast)
I don't recommend you read this, but if you really want to, I suggest you just read chapters 2 & 5 and skip the rest.
