about the "
internal conflicts about themselves or life", there are...plenty!!! No really, on both side of Tatsuya and Miyuki.
Also, this LN is not about might vs might. It's more about how you use your power. Tatsuya himself is at the top of the world in term of destructive prowess, BUT he can't just go and destroy the world, can he? He did struggle in many of the fights, yes he had to hold back a lot due to many reasons (which are interesting by themselves)
About the plot, well, it's not save the world like Naruto ATM
, if I had to sum it up, then I guess "it is about Tatsuya struggling, not in term if power, but in many aspects to fit in and perhaps change the world (for his imouto
)". *Note: it's not revenge like in Code Geass
