Unmei Taisen (S01E02)

With the knowledge that Hikari's illness may be cured if he is the last one standing in the "Fated Clash", Akina gains a sense for Vanguard under the tutelage of Nao, his senior from his part-time job. However, as if his line of thinking was foreseen, Gabwelius appears before Akina once more. (Crunchyroll)
