What if non-hero AU Hisashi was in the Yakuza and sent lil Dk to...

(And then the kidnapping happens)
She had a small crew with Mitsuki and Masaru and the three of them are all in a casual thing.
Hisashi says he will not leave his job but he will provide for Inko and the baby and might get involved when the child is older.
“Why?” Inko asks.
The only one who saw what went down is little Bk who thinks nothing of it at first until he sees Inko frantically talking to his parents that night that Izuku never showed up at home!
But what about Bk?
Well the thing is Hisashi sees a potential future bodyguard for his quirkless son in Bk and decides to start training him up on the skills he needs.
When Dk eventually hears about this he is like “Well that just means Kacchan is gonna be married to us too!”
(In life and in bed too!)
