Kousei probably meant not following with Akyuu being angelic, but i just realized that Akyuu asked Hecatia to make her a messenger, which could also be why she wouldn't exactly follow.
Being direct messengers and agents of gods, Clownpiece and Reisen for example are technically angels.
If you mean like a valkyrie or something, sure! That might work for the physical side of things.Right, then...So. Reincarnate the way you are, except a valkyrie? Got it.*FWIP!*Looks like we're almost out of time.I'm nooot really sure I follow, but...Oh my.WE'RE JUST CUTTING TO THE CHASE!?Yeah, that! Valkyrie! That sounds awesome!Well, y'know, I'm just doing it as a bonus. The real point is to get you back to Gensokyo, so... no need to overthink it.I hope you enjoy...your brief reincarnation in another world.
