In order for Kawaki to become a genin, it’s decided that he can take a special test that differs from the one held at the Ninja Academy.

Wenn du stärker werden willst,
Si quieres hacerte fuerte,
Si quieres hacerte fuerte,
Se vuoi diventare più forte,
Se quer ficar mais forte, não tem escolha,
Если хочешь стать сильнее,
 придётся работать бок о бок с товарищами.
