Unironically Chuuni progression fantasy stories?

I know it's fun to make fun of or do it ironically or for laughs, but are there any series out there that just fully embrace the chuuni vibes.

HWFWM is an example of a series doing it ironically (or at least tries to), but I'm looking for a series that is extremely over the top about it AND plays it completely straight. No attempts to make fun of itself for it or anything.

Chuuni to me is stuff like 'forgive me for going all out just this once', cool 'set piece moments' where the MC doesn't look at the massive explosion, or tends to have a lot of onlookers oohing and ahhing at their exploits. Stuff in this general vibe. Action anime type stuff.

Edit: I've been educated on proper terminology. Looking for epic stories, with big action moments that are presented with sincerity. No lampshading or self-criticizing. Good, grey, evil MC. Doesn't matter. As long as it's both epic and sincere about it, I'm interested. Not interested in sincere stories that aren't also epic. Avoiding the so called cringe by being more down to earth or realistic isn't what I'm going for. Sincere cringe only please.
