Grelinek is the captain of team Shenkuu, playing as a forward. She has speed and skill, but occasionally lacks the power to slam the Yooyuball into the goal. She has duties at the Lunar Temple. In the run up to ACXI, she started having dreams about her holding the Cup on the winner's podium. In 2018, there were rumours she had problems with Larcy Phu. Mirsha has a girlfriend named Ginia who is the team's head coach.
At first I thought it was just the memories of the previous times I’ve stood on the podium that were playing into my dreams. But then I realized that I was always holding the Cup in my hands, and that’s never happened in reality.
I don’t really believe in prophecies, if that’s what you’re asking about. Then again, my dreams probably reflect the fact that I really want to win the Cup, and I do believe that that can affect how we end up playing.
Hey Timu, could you give me a hand over here with these boxes?
Supplies for Xana’s Yooyuball camp. We were allowed to store them here until we started it back up.
You've come a long way, both on and off the field—and I'm seeing you grow more and more every day. Here's to that ever-rising potential!
Woah, I can help, girl. No need to get them all yourself!
You know, I heard Foltaggio is taking a break on the Isle of Yooyu, since the Cup was cancelled.
I’m glad Foltaggio took a break. He’s always been a hard worker, but it can be stressful when one puts so much pressure on their shoulders.
What do you mean?
If that’s what he wants, what would be so bad about that?
Hmm. I would say there’s no such thing as wasted potential. It’s more important that someone is happy. If something doesn’t bring them joy, then potential doesn't really mean anything.
Well, even if that was true. It’s not up to them how he spends his life. He’s allowed to pursue happiness.
It's not. But you’re allowed to go at your own pace. As hard as it is to slow down sometimes, I know you've got what it takes.
The entire team trained tirelessly during the offseason so we have our new plays down pat, but the fierce competition in the Round Robins proved that the other teams have been practicing just as relentlessly as we have. I’m confident we still have a shot at taking home first, but the pressure is on.
Well we are very close as a team, so we have each other to lean on. Plus, all of our loved ones have been very supportive.
There is a special little usul out there whose eloquent words have always inspired me to be the best version of myself. So, I have to thank Ginia, no matter how embarrassed this will make her, for always being patient with me when I get frustrated with myself. I know I can rely on her whenever I might need it, and that means the world to me. No matter how we finish out this Altador Cup, I already won the day I met you.
Mirsha is the twin sister of Atsumi Grelinek. They also have a non-identical brother, who looks like this:

Mirsha participated as a member of the Shenkuu Yooyuball team from 2007 to 2024.
