A short manga on how Onizuka and Danma got to know each other. It has some cozy vibes of past childhood days with friends, but that pretty much it. Is has some fighting but fewer jokes than SJG. Seeing younger and more innocent Onizuka and Danma is pretty enjoyable too. It also feel like a lot of stuff could be covered in Bad Company since if feels like a big gap between in and SJG. But that's ok, it's a story for another time but it leaves you wanting more. So check it out if you want some more backstory otherwise you can probably skipit. Don't expect much, it's only one volume.
