Honestly, the story concept has potential, but then again, the author is adding an anime superpower, and then 'balancing' the abilities for 'realism' is total BS. If you are adding anime power, don't destroy them for the sake of 'realism'. If you want to lower the Sharingan power, just use the concept of the seal. Unlock new abilities of Sharingan as MC levels up.
So, it's not my cup of tea.
