Kanji= (あ、そーれ) (あ、よいしょ) (あ、そーれそーれそーれそーれ)

「俺は単独で正義活動をしている サイボーグ、ジェノスという者だ！ 高速接近反応……来る」

強さの秘訣が知りたくて 日記に記すのさ

「俺には倒さねばならない宿敵がいるんです！ サイタマ先生、俺を弟子にしてください！」

For the sake of avenging my family I took this body from the doctor Now is the time to eliminate evildoers With these red-hot flames “Wanna know the secret to true strength” I write in my diary~ (Ah scribble, scribble, scribble!) Toilet scrubbing is also in my daily routine One-Punch Marching Song~

“I have an arch-enemy I must defeat at all costs! Saitama-sensei, please make me your disciple!”

(Ah, c'mon c'mon c'mon!) One-hit KO, One Punch One-Punch Marching Song Dancing, singing, and fighting One-Punch, ah, Marching Song~
