Well, this was a really good show by studio madhouse,
it's described as a sci-fi romance, and visually it was stunning,
It's got a very unique style to it and a lot of dark and heavy themes,
I highly recommend it.

This charater is Kaiba, the main guy, but it's set in a future where you can swap bodies, and the rich can do this indefinitely, allowing them to live forever.
The body he is shown in now belonged to a girl named chroniko who led a tragic life, she thought her memories would be saved so she could someday get a new body, but a corrupt doctor simply released her memories, killing her for good.
she sold her body (literally) so her family could have money to start a business.

I believe it is very unappreciated as a whole, not just this character, but the all the characters, and the story itself.
