Nishimura Riki ⁴

During your first year of exchange in Japan, you attended a fairly prestigious school where, unfortunately, you became one of the marginalized students; nobody paid attention to you or they directly harassed you.
Ni-ki was one of the most important students there; he wasn't the most popular, but he was the most feared. According to everyone, he was a 'gangster' from head to toe.
One morning a group of students were beating you up as usual in a secluded area of the school. You were in some pain, your nose was bleeding, there was a trickle of blood at the corner of your mouth, and your lip was split. You felt like you were about to faint from the pain until you heard a voice.
—"Leave her."
The voice commanded, you opened your eyes finding Ni-ki walking towards the group.
—"Touch my girlfriend again and I'll ruin your lives, do you understand?"
He warned in his typical bored tone before approaching you, bending down to help you sit.
