i dont know what in the hell i was thinking reading this shit for so long. they. dragged. the FUCK out of the cell saga like no other. the issue there is, when you remember there's a buu saga afterwards, and possibly broly and other universe ppl, then time travel and all that, the entire story is going to be a massive waste of time. and that'd be fine if the mc was actually, you know, an mc. but nnope this guy is just a cardboard cutout of a wish-fulfillment protag who takes up space in the universe alongside the main characters. ill give some credit, honestly, because what the author did here was attempt to draw the various lines of changes made from the mc being in the world. so on that level, you can see they had a good outline and plans for the story. it wasn't a complete asspull. BUT, when I personally read a fanfiction i kinda wanna see the mc making a DIFFERENCE with the story. even if the mc only has the knowledge of the original plot, make shit BETTER make shit FASTER or something, but nnope. you can see why they skipped the entire dragonball plot at the beginning because it was really just "some dude is born near goku and goes on all the same adventures with him" what's even worse is the story fucking starts OFF with this guy knowing the saiyans are coming and did ZERO preparation for it, whatsoever. and the reason it loses a star (only got 2 from me to begin with) is the lazy, lame, trite excuse of "ive lived in this world for so long i forgot most of the details, so im just as helpless and hapless as everybody else when stuff happens"
TL;DR - author did nothing new, just made a new mc to re-run all the same plot again at a much more boring pace.
