i can already see ren saying something like "What have i done to deserve this?"

hinata has learned well

the clone emperor is sad

welcome to chinese novels, any power or ability you see here sounds like that

thats a good question, idk, i feel it counts?

No harem, as for why: there is no reason to have one, as you have already said, you have nothing in particular to gain with that and i feel those would simply be extra chapters with almost nothing happening, meaning of no plot nor development for most characters unless you center more chapters to romance (which for some reason almost never happens in most harems... yeah i hate most harems for that...), but if you think you can have a good balance of plot, romance and development between each character (mark, mikasa, lelouch, goku and/or x member of the harem or side character), if you really feel thats the case, i think you should go on as you please. As for lelouch, honestly i dunno, its hard to imagine him having romantic relationship with a women, not to mention a complete harem... but if its only something he would do for his objectives, then it would be totally possible, though i steel feel it is something he would be against to, not only because it would make him feel like his father but also because having childs in that kind of situation(which would likely be an important part for those kind of agreements), in a marriage with no love with many women, could make him feel distant/detached from them, which would make him feel worse, since the comparison towards his father would seem even more correct... fuck now i kinda wanna see it, imagine the tension, the drama.

... you have to give her berserker, imagine how fun would that be
