Frankly, this is absolutely genius. Better than canon in my opinion

Chuuni!Raynare is best!Raynare. I would love to see this universe continued. And see how Rias and Sona would react to Yuuma involving them in her chuunibyou. If you kept Rias somewhat in character I could see her also having chuunibyou, but Sona as student council president having to deal with her childhood friend and Yuuma would be hilarious.

It's so adorable how Yuuma tries to stay in character.

Oh man, I laughed so hard at this one. But a pink ruler? That's just not fair, man.

Issei/Raynare is one of those pairings that doesn't work in anything outside of PWP. But this? This was absolutely glorious. Great work!

utterly adorable

This is Raynare as the alter ego of a chuuni, goudere Yuuma. Goudere is one of my favorite archetypes that I've hardly ever seen, and it's favorite for a reason. (A large part of which is this story, which is basically what introduced me to the concept.)
I really, really like it. And I kind of want to see what's happening with Gremory...

What the Frick?

This was quite humorous, though a bit weird.

So damn adorkable...I am dying of diabetes over here...

Adorable!
you are the best at Sympathetic Raynare, in its many incarnations.

I am not gonna lie, chunni raynare is waaaaay to adorable! Lol I love this fic so much!

Clearly, this is better than canon.

I'm being serious right now.

Espero con ansias la historia, Lo mejor que he leído en el mes, Saludos.

Pretty freaking cool. I find that these type of stories make a very nice contrast to the norm. Also, it seems like most of them are well written as well. Great interactions and some entertaining ideas.
