The big reveal that he is doing this to make his mother proud is really great. It properly sums up Akira's character for me. He is the youngest member of the team and that he has a lot to prove to us audience. This is one of those episodes that showed us that Akira is one great character and I can't wait to see more of Akira in action in later episodes. As for the rest of the episode such as the in-suit fight and the giant fight, it's kinda okay. They maintained the quality of the fights from the previous episodes.
