"Horse (Umamusume)"
The kanji for "horse" is written as 馬, with four strokes at the bottom representing a horse's four legs.
As quadrupedal horses do not exist in the Umamusume setting, instead being replaced with the titular bipedal horse girls, the kanji for "horse" in this setting is written with two strokes at the bottom instead of the usual four.
