Review Detail of 5thPleiades in Speedster in Multi-verse ( It is rewritten in the new book.)

The idea is great, however, I didn't like the execution. MC wastes his 3 years doing vigilante work(In my opinion) and leaves Nejire behind. Can't he just train with the villains where he lives? And I don't understand why the author put the MC in the same year as the main cast(He's older than them). I think he should be in the same class as Nejire. I came here to see Speedster ff but all I saw is a kid with a quirk that lets him copy other people's quirks. And I hate the "I'm gonna hide my power until I'm strong enough to face All Might." thing. I understand that's the logical thing to do but I came here to see Speedster ff. At least in the recent chapters, there's some good action. And before I forget, in the last chapter the author introduces other reincarnates. From this, we can say that this will be a multiverse ff with multiple reincarnators. But I won't drop this. I'll continue reading this out of my curiosity. Good luck to the author. PS: If you want MC that gives his all in everything, don't read this.
