smart character(s)

The MC is the princess nobody thought would get the throne. But it's exactly what happens when, to prevent a civil war between the followers of his two talented eldest sons, the king chooses her, whom no one follows, as the futur queen. but the princess is'nt all she seems to be

sequel to Re:Zero kara Hajimeru Isekai Seikatsu - Daisshou - Outo no Ichinichi Hen

in this one it's more like the MC does'nt have a choice,he has tu uses his head! everytime he dies, he go back three days in time. If he does'nt want to live in a loop, while always seeing the persons aroundhim die before diying himself, he better think to find a solution! dark and really intersting! the story continues in Re:Zero Kara Hajimeru Isekai Seikatsu - Dainishou - Yashiki no Shuukan Hen.

tho the end disapointed me a bit, i really love this manga!! a guy finds himself framed for the murder of his mother then goes back in his own past to try and stop the murders where they all began, with big consequences on his own life. the fight between him and the murderer implies thinking smartly, and fast.

the MC travels to another world and find herself in the body of a girl killed by the neglect of her family. since she was a mercenary leader in her previous life, she uses her incredible tactical knowlege, wits, and assassin skills to change the situation, soon finding herself in love with one of the princes, and helping him become the heir among the plot of the court. BUT she's too smart, and her past life does'nt explain her perfect knowlege ofeverything (poison, court politic) now

the MC is the tactical counsellor of the daughter of the emperor, one of the potential heir. he can't fight and his only skill is his tactical knowlege. LOVE the possibilities, but too few chapters to juge...

Again a MC who has less powers than others and who can only uses his brains to compensate. i really like this kind of plot! every child is now born with the power, called iris, to see something, different for each person. And our hero is one of the rare ones who has'nt that power, but uses his brain to compensate and solves situations. really really like this one!!!

his father was one of the best general of the kingdom, who was put in prison for refusing an order, his teacher was the scientist who created the word "science", and he was forced to leave the kingdom on accusation of heresy. formed by these two mentors, the MC is a tactical genius, tho he's not good in physical combat. Exactly the kind of MC i like. this manga is based on a novel (which i have'nt read) and has a very good anime

when you're trapped underground by an earthquake, with little food, no idea when rescue will come and not sure you can trust the people trapped with you, you better use your brain fast to survive.

the main does'nt have any power in a society where everyone has one, and where the strongs have every rights. so he uses his intellect
