Kensei Amagiri

Kensei Amagiri is the main male protagonist of DxD - The Last Amagiri. He is the survivor of the Amagiri Clan, a clan of mystics and demon slayers who served the Shinto Gods since ancient times. Soon after the unknown massacre that occurred leaving him the sole survivor after the death of his mother. He is kidnapped and brought into Hagun Island, an island on the coast of Japan that also acts as the base for a tournament named Gehenna owned by a man named Taro and sponsored by the Old Devils interested in children with special powers.

He later becomes the adoptive brother of Claire Belial, the daughter of Cleria Belial and Masaomi Yaegaki. Kensei is later sent off the island after hearing a couple of Old Devils talking about Claire and her parents to a location filled with malevolent youkai before being saved by Sun Wukong and Yu-Long. After informing the Chief-God, Amaterasu about the situation, the Monkey King decided to take him on as a disciple for the amount of time that he had left.

Appearance
At first, Kensei was a ten-year-old with black spiky hair and gray eyes that seem to radiate fighting spirit. As a result of the unjust conditions of Hagun Island, he is mostly seen to be dressed in light clothing that grants little protection. After his training with Sun Wukong, Kensei gained a more toned built along with wearing a black gakuran unbuttoned school uniform, a blue undershirt with the kanji for his name on it.

As a sixteen-year-old, he is a young man of average height with his turning a bit spikier than before; due to his training during that time, he has developed a well-built and a clean-cut figure that Alice states are close to perfect. He is often described by women as being the perfect combo of cute yet handsome while being strong yet kind.

Personality
Kensei is a strong-willed and noble young, even in the heat of combat he always maintains his composure when faced with a dangerous monster. Whenever fighting in Gehenna Tournament, Kensei developed a Win or Die mindset after stepping into that ring or when faced against opponents far more powerful than him; Alice describes this as being an instinct developed for him to survive. This mindset while in combat, however, is held back due to his hesitance in using his clan's techniques or swordsmanship during his matches since he refuses to use their techniques in a greedy sport.

Outside the Gehenna Tournament, Kensei acts like any child his age; he is a caring brother to his adoptive sister Claire and generous towards his friends and allies like Alice, Zane, Hisui, and Rui. Like any protective older brother, he is adamant about letting Claire join Gehenna even with him knowing that she is fully capable of taking care of herself. As said by Alice and Claire, he can sometimes be very dimwitted whenever it concerns with dealing with a woman and a bit unknowledgeable about their feelings towards him.

Like a true martial artist and swordsman, Kensei holds the ideals benefitting one. He enjoys fighting strong people particularly those far powerful than him desiring to test himself against them to further develop his skills. This desire to fight strong opponents has led to many people calling him a battle maniac.
