Hello I need help with the online achievement pls

The game is on a really good sale at the moment, so I was thinking about buying it. But I also realized that the game have some online achievements, and the game seems to be quite low on players especially when compared to Umamusume: Pretty Derby. Also can you still go in online and find players, or do you have to ask people to join at the same time in order for the online games to start? ...

I now have the achievement but am willing to play with anyone who needs help getting it just hit me up.

well the title explains everything

help me to get the achievement
