They are a mob family thier just the 10th generation of the mob family but just like the last generation they dont use thier power to threaten but to protect they go to mob sit downs they take out a family but how they do it is they dont kill but beat the mess out of them with weapons and abilitys but they are a mob just the 10th generation is made up of nice high schoolers who like to help people
Ok so they're a band of merry men. A group of vigilantes, an anti-mob. All of those fit better, you don't go to Sit Downs to fight actually, those are supposed to be where other families talk and negotiate and whatnot. I don't see evil mobs even agreeing or wanting anything to do with a family who isn't dirty and wishes to do good things. Are these other mobs grown men losing to kids or evil kids losing to kids
Some mob families are made up of a new generation and some are grown men but the mob family my character is from is the strongest mob family that train each generation to be as powerful and stronge a the first generation or try to exceed that power but they do go to sit downs to try and stop unnessicery fights before they happen and people get hurt some people are reasonable but some arnt and later on try to attack them so they defend people and themselves but they think of people before themselves like my guy would take an explosion to save someone
When I read about this good mobsters thing, I can't help but think of the Pianta Syndicate from Paper Mario.
And having just looked up Hitman Reborn, Regelion's character seems to be based heavily on Hayato Gokudera, sharing quite a few abilities.
