I wasn't able to find out anything about "Oudou Rosen" (王道路線).
isn't it a type of news publication for horse racing iirc? If we take it literally, it should be "Winning/Ruler's Road". I've seen the term used when someone/something makes a winning comeback from break due to injury or something.
New YearsHappy New Year!Ikuno, you said it, right?The attention this year is on Efforia!
My achievement at the Oudou Rosen has slipped away!
You said my future looked bright and that my saddle was in great shape!Efforia is a 3 year old race horse.
Wikipedia:EfforiaWhat about what you said, Ikuno!That's why!
The goal for this year's Turbo Racing......is naturally this result.*GLASSES PUSH* !"That's valid"!
