Yagami Raito
The opening of every story does not seem as world-shaken as people's assumption. In this world, believable and unbelievable things always happen, only some of which are not known.
At least an unbelievable affair happened to Yale Right, who should be called Yagami Raito at this moment.
If she did not die, if she did not major in law, if she did not watch the manga "death note"…
There exits a lot of "if"s which count a lot of embarrassed deciding choices in life. Yale Right is not the kind of person who tends to complain like, "if I", so she lived in accordance to with Yagami Raito's natural tendency.
From then on, the subject of Yagami Raito was substituted by "I", the hope and desire that were not realized by Yagami Raito, will be accomplished by me.
