In fact, the relationship between Beichuan Si and Shen Gu Mirai, as seen through the eyes of outsiders, was simply that one was the Kyubei North Demon King and the other was his deskmate, a cute little girl who often talked to him.
After all, no one could imagine what it would be like for Beichuan Si, the Kyubei North Demon King, to have a girlfriend.
Those little girls who claimed to be Beichuan Si's girlfriends were indeed more interested in him, but their interest was merely that.
If they were really to become Beichuan Si's girlfriend—
They probably would've been sunk in Tokyo Bay the next day.
The most direct result of this was that these delinquent boys came to intimidate Shen Gu Mirai.
Beichuan Si flicked his fingers and, without deigning to look at the bruised and swollen gangsters on the ground, turned and walked away.
After a bout of 'friendly exchange' and cordial 'touching,' these delinquents had tearfully agreed to all of Beichuan Si's demands.
