ばか！バカ！　馬鹿ー月！

A guy(probably cursed?) is working to help people in trouble. Appointed by his teacher(also someone he admires), he is to take care of a young girl(more like tricked to take care of her). This girl is arrogant and straightforward. However, because of her boldness and straightforwardness, she becomes like sun to the protagonist, since the protagonist seeks death to some extent, and has a lack of confidence. However, unlike most novels, the protagonist has quite a reason for the way he is, unlike most other novels. When he was young, he went overseas with his family. Sadly, his family was involved in a terrorist attack, and his parents and sister all died... Leaving him all alone...

His childhood friend's family took care of him, but he has always wanted to die, so as to join his family. However, he is afraid to take his own life.

One day, his childhood friend dragged him out to cheer him up and have fun. Unfortunately(cursed, isnt he), they encountered a foreign children abducting group. All the children cried in fear, and some were killed, shot in the head etc. As the abductors are trying to get his childhood friend, he steps forward, hoping to die. However, instead, a woman came forth and thrashed these abductors. Deeply in awe of her might, he requests her to take him in as her disciple... And thus started his new life.

I watched the anime first, so i am able to visualize it more easily. In the first volume, it went till the protagonist snatching murasaki back from her family. However, there are differences with the anime. For example, The anime has a lot more stories before the fight for murasaki. At the same time, the ending is slightly different. In the anime, Murasaki chose to go back to the family and fight against the might of the family. In the novel, Murasaki was given permission to join the outside world. But she still went back to the protagonist's side.
