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—
And until I die, I won't let you die either.
وقبل أن أموت، لن أدعك تموت أيضاً
Und bis ich sterbe,
wirst auch du nicht sterben.
Y hasta que yo muera,
tampoco dejaré que mueras tú.
Y hasta que yo muera,
tampoco dejaré que mueras tú.
Et tu ne crains rien
tant que je suis là.
E finché non morirò io, 
non potrai morire nemmeno tu, Yu.
E até eu morrer, não vou
deixar você morrer também.
А пока я жива, я не дам умереть тебе.
