Ryotei-san?She's now pissed off...!!That peculiarity gave you the nick name.And it's allegedly also a pun on "bad girl"...
阿寒湖 and あかん子 are both spelled "あかんこ"But in your case, the only victory you have to your name is the Pre-Open Akanko Special from 2 years ago...Most girls who run in the G1 races have at least one group race victory to her name...I WILL SOOO NOT WIN!!For the last two years, you haven't won a single race.And with that next to your name you keep running in G1 races.
