Detroit Metal City ova - Roppongi?

Go to DMC!

I love DMC ova!
Just finished 2nd ep of Gymnastism anime and notice something that said by tsutomu-kun was somewhat caught my ear...

Negishi-san omedetou~

After a lil bit of research ... nothing particularly interested me but this...

"Roppongi had a reputation as an area with high Yakuza presence..."

Well...
There's some pics as solid evidence.
Yakuza (s) do appear a lots and lots through out this anime.
Including the 1st season~

Their 1st appearance in 2nd season~

whats with that pose.

Driver-san + Aniki-san = Funniest couple.
