"This might sound cocky, but I want to be my own person so I can stand shoulder to shoulder with you."

VAZZY's brothers Issa and Futaba Kiduku receive an invitation to co-star in an original drama series. At first, older brother Issa is asked to play the straight-laced big brother Ryo and younger Futaba is asked to play the reckless little brother Itsuki. However, on the advice of show planner Taiga Orihara—an old rival of Issa's from his rock band years—the roles are reversed. While Issa's genius-level acting skills allow him to slip into his role with ease, Futaba struggles to take on the persona of an 'older brother.' Fellow Tsukino Productions members Haru Yayoi, Shiki Takamura, and Gaku Oguro then show up to form a new group called The Oniichans and teach Futaba what it's like to be a big brother.
I'll do my best to show Issa
that I can be his rival.
.سأبذل جهدي لأري إيسا أنني أستطيع أن أكون منافسه
Ich werde mir viel Mühe geben,
damit Issa mich als seinen Rivalen anerkennt.
Me esforzaré para que mi hermano
llegue a considerarme su rival.
Me esforzaré para que mi hermano
llegue a considerarme su rival.
Je vais me battre pour être reconnu
comme un rival par Issa.
Farò del mio meglio
 perché Issa possa vedermi come un rivale.
Farei o meu melhor para mostrar
ao Issa como posso ser o seu rival.
Я постараюсь показать Иссе,
что меня можно считать соперником.
