Gonna be honest, it is a meh type of story. It's "transmigrated" into Saitama with his powers so it is obviously that you should't expect anything serious from it. But, it stays strict to the true plot with little to no change which makes me question why even am I reading this. Sure, he gets power ups but... what is the point? He is already overpowered with Saitamas power. If it was "I transmigrated into saitama, don't have his power but obtain a overpower ability after doing quest" type of story it would be much better because then the plot would at least change a little bit more. My Fubuki ship went down the drain when you turned her into a transmigrator too. The grammar is average in my opinion too. Lines are striaght to the point, we lack some descriptions on some people or actions but overall it is way better than some chinese garbage. 3/5 seems like a good vote. For people who are bored and want to read something chill.
