TL;DR Forget Kirito and the other hundred pretenders of being the isekai chad, Anos Voldigold will kill them with his heartbeat and by blinking (actually happens in the show). It's actually funny. Watch it if you're isekai trash!!!
Long version of the review ahead (with spoilers!!!!)
Story - 7
The overall plot is slightly above average. You're probably not going to watch this for the feels or the deep moments. It's typical isekai trash
However, the story is enhanced by the over the top renditions of cliches. The op mc kills with his heartbeat as mentioned previously, dude drains a lake by exploding, he defeats time itself??? So comedy wise it's really funny if you know all the cliches already.
I almost forgot but at one moment the mcs FANCLUB STARTS SINGING TO GRANT HIM MAGICAL POWER, which overpowers the combined efforts of 10 million people. Like, wtf, it's hilarious
Art - 7
Honestly it impressed me, probably because my expectations were non-existent. The anime actually has some cool special effects and sometimes the 3D CG works in its favor cause the graphics look so dumb yet so detailed.
For reals though, there are some impressive graphics sometimes.
Sound - 6
Sound was average, not much to say. The OST was forgettable. I watched the dub and the voices did not hinder my experience. The idol songs were really really average. The sound didn't let the show down though, it was just generally forgettable
Character - 7
Anos Voldigold is a chad, he carried the show. He is charismatic and impressive and he left his mark for an isekai character. The other characters were generic af.
Small footnote for characters: Somehow I got Code Geass vibes in the last few episodes between 2 main characters. I almost think that the creator intentionally made references to Code Geass characters. Since the dynamic between Lelouch and Kururugi from Code Geass was so good, just seeing a hint of it inside this trash isekai anime somehow made it kinda emotional ;-;
Enjoyment - 8
It's funny.
Overall - 8
Watch it if you're an isekai trash lover and want a guaranteed good time.
