Yuuhi learns of the reason Samidare wishes to destroy the Earth, and he continues to train himself every day in order to hone his new powers. However, the "discipline" Yuuhi received from his grandfather continues to bind him like cursed chains.

During that time, Yuuhi receives word from his home that his grandfather has fallen ill and been hospitalized—
I'll try my best, 
so please don't abandon me.
سأبذل قصارى جهدي، لذا لا تتركيني أرجوكِ
Ich werde mir mehr Mühe geben,
also bitte gib mich ni…
Me esforzaré, no me dejes.
Me esforzaré, no te rindas conmigo.
Je ferai de mon mieux,
ne me rejetez pas…
Ma ce la metterò tutta, 
per favore, non mi abbandona—
Vou me esforçar.
Por favor, não me abandone.
Я буду стараться, только не бросай.
