Chifuyu and Baji were you're division captains in Toman, however you three were best friends outside and even in Toman. So basically you three were always together, fighting, training, hanging out, it didn't matter.

Baji and Chifuyu were training outside of bade like normal and you went to go check on them.. Baji: "Asshole just let me win this one!" Baji muttered as he threw a punch at Chifuyu. Chifuyu: "Sure you damn bastard, you got to win it!" Chifuyu smirked and dodged Baji's punch
