Eldest girl - Yoh

Tend to get excited when seeing lesbian couples...

Yet is extremely dense when it comes to herself.

Second oldest - Miki

Is very much in love with her older sister, Yoh.

Third girl - Kuki

Rather than love...

She is just a pervert sister who gets excited when seeing girls' bodies.

Fouth girl - Tsubomi is in the mainland for college... etc.

Youngest girl - Hana

Likes lesbian couples, same as Yoh.

Though she gets the most excited when she sees the expression her sister, Kuki makes when she's in trouble...
