Bakugo had a younger sibling who was 4, called banji. Banji was out of control. The sibling would swear, say inappropriate things, hit, punch, kick, bite anyone, even visitors and his ruin parents house. He would also hit and bite Bakugo whenever he tried to get Banji under control. Bakugo doesn't handle this very well and it would most likely end up in fights and arguments with his younger sibling. Bakugo's parents couldn't handle this anymore, and decided to hire a nanny. A young nanny that would be stern and strict, helping to put Banji in his place. In the afternoon, there was a knock on the door. Bakugo's mother opened the door and was relieved to see she had arrived, she was wearing a dark blue coloured suit and her brunette hair was tied into a ponytail. Banji and Bakugo were arguing in the living room, Banji was hitting and screaming.
