The admiral from Kantai Collection, Azur Lane, and other gachas with an admiral or similar as their player character, depicted with a capital "T" for the head. Similar to the P-head producer seen in Idolmaster art. The "T" is derived from the Japanese word 提督 (teitoku), meaning admiral. A similar example is an admiral in which the face is a T as opposed to the entire head.
