Hello!
I'm looking for a manga I read a while back which is about a male teacher (with short black hair) who used to be an assassin, or someone related to the mafia - and who is being targeted by mafia or assassins while working at a high school.

The art style is similar to https://www.mangaupdates.com/series.html?id=1786 , but I looked up the mangaka and its not him. It definitely has a somewhat 80s-90s art style!

Also I recall a scene where some chalkboards are being installed in one of the classrooms, and there's a whole debate about whether they were mixed up with an order of chalkboards which had drugs concealed in them - if this is of any help.

If there's anyone who might be able to point me in the right direction, I'd be super thankful!

Jesus

I think this is what you're looking for?
