Motoko Aoyama

Motoko Aoyama is a main character in the manga/anime Love Hina.

Background
Motoko Aoyama is the younger sister of Tsuruko Aoyama who was heir to the decling sword school the Shinmei Ryu she was very close to her sister adoring and idolizing her.

One day Tsuruko got married and gave up her title as heir but Motoko chose not to be happy for her sister feeling she was being taken away and not understanding why she would do this she came to hate men and one day came to live at Hinata Inn where she met Naru Narusegawa who had a similar mentality to men as hers.

One day Hina's grandson Keitaro comes to Hinata Inn...

Personality
Motoko is very arrogant, bossy and with a hatred to men regarding them as weak and perverted. While Motoko can be bossy and controlling it is not at the level of Naru but she is just as guilty of bullying others as she is including the other Hinata Girls especially Shinobu.

Motoko regards things like love and femimity as weaknesses thus holds them in disdain and cannot come to terms with anything she feels for Keitaro that is not hatred.

Like Naru, Motoko would often re-interpret the most innocent or accident Keitaro has as a 'pervereted thing' and would violently assault him ignoring anyone who tries to tell her he did nothing wrong.

Also Motoko is very hypocritical she talks of honor and yet she assaults unarmed, harmless and/or innocent with her sword also Motoko talks of being a samurai (ignoring the samurai class was fully abolished in the 1870's) and yet violates every aspect of Bushido.

However unlike Naru later on the manga Motoko would be redeemed not through Keitaro but eventually by her own sister who finally got her to face up to reality, her feelings (including feelings she had for Keitaro) and herself. After a duel with Tsuruko near the end of the manga its then Motoko finally matures and becomes a better person.
