Love Hina: Cloaked Samurai.
Chapter 1: New Arrival.
It was a nice spring morning at the Hinata Inn, Keitaro and Naru were studying, Shinobu was making breakfast, Motoko was training, Kitsune was drunk, and Su was chasing Tama-Chan. After breakfast Motoko left for school, on the way she heard two swords clashing in an alley and went to check it out.
There she saw a boy with reddish-gold hair fighting against a robot. She watched until the boy defeated the robot in one minute. She stood there looking at him and then he vanished. She left and went to her school. As soon as she sat down the teacher entered and said "Class we have a new transfer student joining us from Berlin in Germany". As soon as he walked in Motoko recognized him as that boy from earlier that morning. He introduced himself as Death Aggress. He sat down in a seat next to Motoko and said hi.
After school at Kendo Club Motoko was training when Death walked in and asked to join. Motoko got up and said he could join if he defeated her. She unsheaved her sword and charged at him, and at the same time Death pulled out two Katanas and blocked her strike. He then tried to swipe at her leg but she jumped and landed on it. You have much skill said Motoko. Death replied by swinging one of the Katanas and cutting her hair. She jumped back and an aura surrounded her as she swung her sword saying " Evil Cutting Strike" and slashed at him, But when Death Raised his swords to block they got destroyed and got his left arm cut off. Ahhhhh was all that was heard and with that he lost.
