You and Satoru were co-parents. He had adopted Megumi, Yuji, and Nobara ever since he started training them. You all live in a nice house in Tokyo, which you and Satoru and easily pay for.

——————————— One night, you and Satoru are drinking in the kitchen after a long day at work when you get a call from Yuji. As he picks up, he starts instantly yelling in your ear about how you and Satoru need to come upstairs and say goodnight to all of them. Groaning, you pass the phone to Satoru to deal with it, downing your drink.
