When Hinako Nakayama took on the identity of Hikaru Onigashima, she didn't know what it would mean for her future. Now, with the support of the friends she's made with her martial arts skills, it's time to prove who's the boss of Shishiku Academy!
I swore to get stronger,
،أقسمت أن أصبح أقوى
Ich hab geschworen, ich werd stärker
¡Mejoraré y algún día 
pelearé contra Hikaru!
¡Me haré más fuerte
y un día pelearé contra Hikaru!
J’ai promis de devenir plus fort…
Ho giurato a me stesso che sarei diventato più forte
Eu jurei ficar mais forte
Я поклялся улучшить навыки
