Koken Gentoshi

**Koken Gentoshi** (阮蔡康健, Gentai Koken) is a member of the Gentoshi family and the deared child of the family. He is the main character of "Sitting next to Koken-kun" and an important character in "I Want to Change Fate".

## Profile

### Background

Koken is the first son of Kazuya Gentoshi and Nobuko Gentoshi, little brother of the well known Yaksha Princess, Sakae Gentoshi and bigger brother of Regina Gentoshi and Anxien Gentoshi. When he was born, he was blessed with great luck and mana which makes him the dearest child of Yue Gentoshi. His life is pretty peaceful. He entered "Highschool of the Gifted" during his highschool life.

### Personality

Koken is lazy and selfish. As he is blessed with great luck and the Holy Grail, almost all of his wishes were fulfilled but rather than using his luck for someone else's sake, Koken only wishes for himself. He never considers other's well being as long as he is fulfilled. Koken is the type of man who never tries their best to do something as he is fine with the current state. He is described as "just living is enough", never tries anything new or different, never truly interested in something.

However, it would be false if you say he has no personality. Actually, Koken is really attached to his tranquility life style. He wishes to live a peaceful life forever and has no problem "dealing" with anyone who dares to destroy it. In "I Want to Change Fate", Koken's solution to the situation is said to be brutal yet extremely efficient compare to the Hero's solution. He has no problem for his host killing innocent as long as the host doesn't cross the line and the purpose was achieved. He is also shown not being guilty or sympathy towards his host, the one who suffered from his childhood.

He is also listless and emotionless. He simply just walks away when seeing people dies in front of his eyes stating that he has no bussiness with them despite he clearly can save them or revive them.

Eventually, he never loves anybody. He feels grateful for being born by his parents but not really loves them. He is basically "too full to love anyone and he is loved too much so he doesn't need more". Yokoi Ruri is probably the only friend he has due to this edgy personality.

Koken is also deep. His poem is surprisingly touched. This confirms his understanding of people's emotion. He is said to know it but don't care about it. To Koken, emotion is not something to sympathize but document. He is clearly introvert as he doesn't really want to communicate to other people that he doesn't know well.

### Appearance

Koken is a plain young man who has dark hair and green eyes. He is described as "An ordinary boy who lives an ordinary life in an ordinary world". Although it is not really true with his luck and power, his appearance is truly that ordinary. If life is a game then Koken is a mob, not even an NPC character. He is usually seen with his uniform, white T-shirt and Jeans.

He also has a chinese robe with dark green color.
