Eichi Tenshouin

Soft-spoken and articulate, Eichi presents himself with the general elegance of someone raised in high society. He generally emotes with various shades of faint smiles regardless of situation, and treats most situations with an airy lack of gravity and general interest, with a preference for the wild and unpredictable. Very little breaks his cordial demeanor, and, should something upset him, he would rather tuck that away at his breast and return the favor tenfold later. He is inclined toward childishness in regards to how easily he is entertained, and how petty he can be.
Beneath his politesse, Eichi is both ruthless and trash. He will fall short of no machination to gain what it is he wants, but his underlying motivations are largely good— he wants to create a better future for the generations that succeed him and his peers, so those younger will not have to suffer the way their predecessors have. However, what makes him so contentious among his peers is that Eichi always opts for efficiency: being terminally ill, Eichi has very little time and very little experience with the world, and so he chooses the fastest—fastest being often the cruelest—path from A to B, as well as the path that offers him the most entertainment.
Eichi has lived most of his life confined to a hospital bed, so weak that he was often unable to even feed himself; when he was able to leave the hospital, he was friendless and isolated, surrounded by vultures who wanted to climb into his good graces as heir to the Tenshouin Zaibatsu, the largest conglomerate in Japan's entertainment industry. This has left him, in short, lonely; his only company for a long time was watching idols on the hospital television, as well as movies and books. In a less tragic assessment of affairs, this means he is clumsy with basic social concepts like friendship, and he is long-winded and dramatic from having socialized mainly with movies and books.
I HATE YOU. YOU ARE KIND OF UGLY
