He is the main character of the Shironeko Project: ZERO CHRONICLE
Which I reviewed here, which is about my perspective on the episodes that I watched which is 1-9

Now, about him. I found this character as a very heroic character type. He wants to save the Queen of light Iris whenever she is in trouble. When someone is being hurt like on the early episodes he cannot stop blaming himself as he did not save them. Now that is the cons of being the heroic type. It’s that sometimes you forgot yourself in order to save others. Anyways even if he is a Prince of Darkness. His will is full of goodness in him. Which is quite a play when everyone associate darkness with badness. The symbolisms have some puzzles to be demystified because in realities. Light and Darkness should be balanced. This anime makes everyone realize this with the main character which is a Prince of Darkness.
Anyways I hope you liked my review..
