Lan

Lan039s actual name is simply C it039s Gingetsu who decides to name him Lan Ran. He was called C because he was one of the threeleaf clovers that once existed and those triplets039 names were A B and C. Now he039s the only one living left and as he039s living away from the Clover Project research facility he039s aging quickly that039s why we can see Ran as a child in the last volume flashback and as a boy in his late teens or even early twenties in the other volumes even when two years have passed only since he met Gingetsu for first time. Actually his life will end in five years and though he knows it he still wants to be away from the facility... and not only because he wants to be free but specially because he wants to be next to the person who039s most important to him. Ran039s character isn039t much developed until the last volume either a flashback to how Gingetsu and Ran met and their relationship began. However Ran is different from Gingetsu: as a child Ran is quite mature for his age but he039s innocent caring kind and doesn039t seem to have any problem expressing his feelings. He doesn039t want anyone to suffer and is always willing to help if needed. He039s sweet and nice but not weak: his existence has been quite hard so far and though he knew it wouldn039t be easy he decided to go for a change running away risking his own life in search of freedom.
