ﾃｲｵｰｾﾝﾊﾟｲﾀﾞﾖ…

I am supposed to be the Teio-sempai here...
Katakana indicating flat monotone.

Notes on titles/aliases:
[expand]
Teio's alias (both the uma and the RL horse) is "Emperor" (different word from Rudolf's). Basically "Teio(u)" written in kanji instead of the usual katakana.

Meanwhile Kitasan (the uma) is sometimes called "Century King" by the Japanese Umamusume fanbase, due to the colors of the track jacket worn by her younger self in S2 of the Umamusume anime resembling Kamen Rider Black's. (cf. twitter #1348952533612433409, as pointed out by a fan). She also has red eyes and her belt buckle looks vaguely henshin-esque. [/expand]
