Akihiko is likely going to continue his efforts of trying to impress this really unconventional senpai trying to create a decent team with Serph. His memories of the Moon Warp are a little hazy but... They technically made a good team? They punched a bear together!

So as a consequence, he probably would be alright with going out to hunt some monster meat after getting over the initial "wait what? WHAT? well if it's still protein." Probably in the form of gorgons, or maybe some bird meat; it's KINDA like beef or chicken. If he pretends really hard.
