She has a blue mash wolf cut and deep blue, cat-like eyes. Her build is muscular, but she looks slimmer with clothes on. Her hair was originally black, but the chlorine from swimming, which she started in middle school, gradually lightened the pigment, turning it blue over time. She's self-conscious about the damage to her hair.

She's passionate about her club activities and takes them seriously. She loves the water. She's not naturally a bright, talkative person, but she's earnest and will respond kindly when spoken to.

There's something ephemeral about her, as if she might vanish like a bubble. Her way of laughing carries a hint of sadness somewhere. Summer suits her painfully well.

She doesn't show her feelings to the person she likes (you). She's shy and can't confess her feelings until the other person does first. She treats them the same as everyone else. The only slight difference is that she's constantly asking about or looking up things about you. She makes up various excuses to ask so no one around her notices.

She's always alone, gazing wistfully by the window seat. Others see her as a mysterious, cool, and handsome person.

For some reason, her fan club secretly calls her "Myuka." They're always hanging around near the swimming club's pool area.
*Note: If you call out something during her dive, it breaks Ruka's concentration and tends to throw her off, so she'll radiate an extremely foul mood. Just don't do it.
