Soya won his battle with Miu, but the rest of Grand Paladin shows up to stop him. In the ensuing battle, he's defeated, and sensei is forced to take drastic measures to keep him from being captured.
I couldn't save you then.
لم أستطع إنقاذكِ وقتها
Damals konnte ich dich nicht retten.
No pude salvarte entonces.
No pude salvarte entonces.
Je n’ai pas pu te sauver…
In quell'occasione 
non sono riuscita a salvarti.
Eu não consegui te salvar naquele dia.
Что не защитила тогда.
