”What are you doing making a poor girl lose face here? ...Just the tip. Just the tip, pretty please!”

Sousuke’s ”current” younger (step)sister whom he’s been with since childhood.

Nanaru is in her first year in high school. She’s cheerful, but innocent too, and she’s a free-wheeler. She’s pretty silly and weird at times, which you could probably guess from a girl who considers her raison d’être to be cracking jokes. The vast majority of her brain storage space is used up on jokes and puns.

She has a fondness for teasing, which amplifies tenfold when her brother is the target. But that’s not to say she doesn’t also love having him dote on her.

”I’ve been wanting to see you... for so long, Nii-san.”

Sousuke’s ”former” younger (real) sister who he grew up with during his early childhood days.

Suzu is in her first year, just like Nanaru, and even winds up in her class when she transfers. She’s a very devoted sister, who’s never stopped loving her brother even after they were separated during early childhood. She’s very docile (much unlike Nanaru), as well as gentle and affectionate. She can be a little bit of an airhead, but she’s a great sister, both in terms of looks and brains.

”Ahaha! Lucky you, Sousuke! Living the life!”

The childhood friend with a fiery attitude.

Maho has been Sousuke’s friend since way back in kindergarden. She’s good at helping people and has a pretty social, outgoing personality. She’s also slightly overbearing, and very competitive. Sousuke actually confessed to her once in the past, but there were several misunderstandings going on which caused her to reject him. At the moment, she is his closest female friend.

”Unfortunately for you, Sousuke-kun, I’m not giving up until you’re mine!”

The upperclassman smitten with Sousuke.

Shiina is the unpredictable type; you never know what’s on her mind. She’s very pushy, and won’t hesitate to invade your personal space. Apart from that, she loves eroge like no other. She sees the world through her eroge googles, which is why she’ll do random things such as suddenly asking Sousuke to choose from a list of choices that decide his next action.
