Cosmic "C"

Cosmic C. Cosmo (コズミックC.コスモ, Kozumikku C. Kosumo), known universally by the letter C (見る, Miru), is an OC. C is considered one of the smartest in Wammy's House whose identity remains unknown to anyone but L. He often takes drastic strategies to confuse and force the hand of his opponents like L. C has taken on multiple difficult cases and solved them.

Character
C, who also uses the aliases Grim, The Blue One, and Cosmo is quite secretive by keeping his identity hidden, and only communicates with the world through his computer. He never shows his face to the world, instead representing himself with a capital C drawn in the "Cloister Black" font (See HERE). He met L in England when he got lost and walked onto the property of Wammy's House at the age of 4, he is an orphan. He also uses the Alias "Ace" as an additional safety measure. only L learns his true name. C's ethnicity is a quarter Japanese, a quarter English, a quarter Russian, and a quarter Spanish. His theme is HERE

C's signature Black T-shirt and Blue Jeans appearance masks his intellect. He tends to second-guess everything he is shown, and is extremely cautious. He has several quirks, such as preferring to crouch rather than sit like L, eating mostly sweet foods (like desserts and chocolate), holding items with his Thumb and Index Finger (as if they were putrid), and oddly stacking objects. C stayed in Japan for four years before he got to England, and during that time he learned how to survive on his own. C, like L, suggests that even though he eats only sweet foods, he remains underweight because the brain uses the most calories of any organ in the body. C also says that if he sits normally, his reasoning would drop 90% because of all the time he has sat like that. It is believed he could have Asperger's Syndrome, due to the fact he acts like a child at points (not wearing socks, eating lots of sweets, and seeing things somewhat like a video game).
