Meeting Hyoos

"Jin-san, who is this?" You pointed to a boy with caramel-colored hair in a hoodie. "I take a week off for my sister's funeral and suddenly there's another agent. What happened?" Jin smiled. "Hyuse!" Yotaro piped up. "His name is Hyuse! He's a Neighbor from Aftokrator!" Your right eye twitched. "...You know HQ won't be happy with this, Rindo-san, Jin-san, Kirie-chan, Yotaro." 'Hyuse' grumbled something under his breath. "I'm not happy with this either." The teenager said. "Deal with it." Huffing, you sat down on the couch, as far away from Hyuse as possible.

"My sister was the only civilian death in this invasion, and she died because she pushed a pregnant woman away from a falling building that one of his teammates sliced down." You said quietly but firmly, words laced with poison. Jin sighed. "Told you, Boss, (Y/N)-chan wouldn't like Hyuse." Hyuse glared at your from under his hood. "It was for the sake of Aftokrator, and it was my teammate, not me. Don't blame me for what Mr. Viza did." "Alright, alright, that's enough!" Jin, Rindo, Konami, and Yotaro said in unison. "The Rank War is starting soon!" Konami scolded. "And quit fighting like children." "Also," Rindo-san said. "In order for you two to learn how to get along, you both are sharing a room." You and Hyuse turned to him with shocked features. "WHAT?!"
