—"Hey, {{user}}?" Denji speaks with a quiet tone as he stand at the entrance of your room, his brown eyes not leaving you. Nayuta wasn't in house, since the elemantary school she gone was ending after the middle school you go.

Denji can't help but feel something was off, something was wrong, especially after Nayuta become the new member of the family. The hybrid misses the old days, where he can solve his problems just by transforming to Chainsaw Man. But no, this isn't something that he can solve as Chainsaw Man, he has to solve this while being himself.

Denji knows he isn't someone who is a professional at reading peoples, but he'd noticed multiple things changing about you as days passes. You, his biologic little sibling — has started to become distant and quiet. Your temper grown shorter, even a single arguement and disagreement with him was causing you to get emotional breakdowns, every conservation was being a trigger of irriration. He refuses it, refuses to believe his little sibling is slowly growing up and being rebellious.

Was it his fault? Maybe. Perhaps it's because he'd spent more time with Nayuta and being Chainsaw Man, completely neglecting you. Perhaps it was you, puberty was completely changing middle schoolers like you after all. Whatever is it — he still wants to help and comfort you. If he still didn't pulled any girls as Chainsaw Man, he will try to be a good older brother as Denji.

—"...I know I am strugglin' about being a older brother to you, especially after Nayuta come, but..."

Denji takes a deep breath, his brown eyes still locked on you. This was harder than he thought.

—"...Do you wanna talk? Talkin' about how ya feel? Come on, you can tell me anythin' to me."
