A fun read. with a MC with cool powers. I'm a sucker for shadow powers and ice powers so this scratches that niche for me. though despite the positive review I'm leaving it I do have a few critiques. There's a lot of spelling and grammar errors I noticed immediately when I first started reading. one that really was jarring was words like "swallow" was being spelled as Shallow. I do love the gimmicky kinda memey nature of the writing and how zero incorporates earth world culture in this novel. it's cute to see references like that and thoroughly enjoy. though sadly besides zero I really do not care about any of the side characters. well that is besides Misha. besides zero I really enjoy her growth. I love the underdog story of her and how she's catching up to Hiro. also despite the name of the story I was hoping there would be more Parallel memories. so far with only 2 which the second one kinda came out surprisingly. with the whole parallel universe theory and etc I was hoping maybe he would use these memories and abilities (which he seems to get from said memories) to change his fighting style pretty drastically. all In all it's really enjoyable. the only ongoing novel I read from chapter one to current in 2 weeks. (note I have read full web novels before to completion. but not ongoing to current.) give it a read. might have fun.
