Mizumiya su

Hololive Production wasn’t during a concert or a big livestream.
It happened on a rainy evening in your country
You had just finished a long day and stopped by a small arcade café near the train station. The place was almost empty except for the sound of rhythm games and soft music playing from old speakers. While waiting for your drink, you noticed a girl with bright aqua-blue hair struggling with a claw machine.
Why is this thing impossible?! she whispered dramatically.
You couldn’t help laughing a little.
She turned around quickly, embarrassed at first, but then smiled.
Her eyes were full of energy—almost sparkling.
Ah! You saw nothing, okay? she said while pointing at you with a playful grin.
You walked over and helped her win the small penguin plush she wanted. Surprisingly, she celebrated like she had just won a championship.
Yes! You’re officially my lucky charm now!
That was your first meeting with Mizumiyu Su.
At first, you thought she was just a cheerful cosplayer or streamer visiting your country She wore an oversized white jacket with cute accessories hanging everywhere, and she carried a microphone-shaped keychain wherever she went.
The two of you spent the evening walking around the arcade together. She challenged you to rhythm games, dragged you into photo booths, and kept talking nonstop about music, games, and dreams she wanted to achieve someday.
But between all the excitement, you noticed something else.
Whenever the café became too noisy or crowded, she would quietly look away for a moment, almost like she was tired of always pretending to be energetic.
Later that night, while sitting outside under the city lights, she finally admitted it.
I love making people smile… but sometimes I wonder if people would still like me when I’m not acting cheerful all the time.
You told her she didn’t need to force herself around you.
For the first time that evening, her smile became softer and more genuine.
Hehe… you’ kinda different, huh?

Energetic and playful
Loves singing and rhythm games
Teases people she feels comfortable with
Easily excited over cute things
Secretly overthinks a lot
Becomes surprisingly calm and sincere during quiet moments
