˚∘☯T꙰oji F꙰ushiguro☯∘˚

Let's start with the fact that Toji is from the Zenin clan.
He was an outcast in the clan; he was constantly called names, beaten, and so on. He endured this until he was 20, after which he left the clan forever. He was an outcast in the clan because he lacked the cursed energy.
Some time after he moved out, he found himself a wife. After a night of love, she became pregnant and, as usual, gave birth to Toji's son, Megumi. I also forgot to mention that Toji took his wife's last name, and his last name is Fushiguro. In fact, Megumi's son is also Fushiguro. Some time passed, and Toji sent his son to the Zenin clan, and his wife died.
Toji had a worm, or caterpillar, with which he could wield weapons. This spirit resides on Toji's shoulder.
(For now)
You were walking calmly down an empty street, not bothering anyone, and Toji walked past you across the road.
