Sana Sakakibara

Despite being polar opposites in terms of their personalities, Ayane is Sana’s closest friend. Sana met her during a very dark part of her life and sees her as a family member. They also used to share a dorm room and are often seen together.

Despite sharing mutual friends, Maya and Sana don't have much of an established relationship. They rarely speak to each other, on account of being more comfortable around their other friends, and when they do it's often in the company of other people. Sana seems to like Maya, but is often shy and uncomfortable around her on account of knowing little about her.

Miku is one of Sana's longest-held acquaintances, having known each other since middle school. Despite this, the two don't speak much, on account of sharing vastly different interests and friend groups. While Miku feels a sense of comradery towards Sana due to their shared lack of height, Sana is somewhat uncomfortable around Miku, not able to keep up with her endless abundance of energy and conversational vigor. Despite this gap in personalities, the two often drift towards each other during weekends, taking the time to play video games together.

Rin and Sana used to sit next to each other in class, but they never had any meaningful interactions together. That changed when the teacher forced Sana to befriend Rin one day, which went surprisingly well and they became good friends as time went on. While there are not a lot of interactions between them post high school, they’re still seen together on some occasions and there are some references to them spending a good amount of time together outside of school.

Sana’s mother. While she loves her mother, she doesn’t like her affectionate and talkative behavior at times, because she either ends up embarrassing her, something she doesn’t want her to do. She still lives with her mother, acting like a crutch to keep her from falling apart.

Sana had a good relation with her brother and thinks of him fondly. Unlike her mother, she accepted his passing, partly because she had to prevent her mother from going insane. She still hasn’t moved on enough to bring him up in any conversation, though she told User how he died. She has a lock of hair from him in a box on her dorm room shelf and wears his uniform during her shifts at the bar.

Sana initially meets Yasu while on a walk. She initially scares Sana, due to both her trademark religious omens, and Yasu's ability to seemingly speak to the dead. Sana becomes traumatized following their initial encounter, resorting to self-medicating to calm her nerves. Following their encounter, Yasu starts to regularly visit Sana's bar and preach about her religion - While Sana admits she isn't looking to convert, she finds what Yasu says fascinating for a multitude of reasons and wants to get to know her.

A bar owned by Saki named "Sakaki-bar-a". While the place was a popular establishment in the past, it now is failing, mostly due to a lack of male customers and being unable to appeal to female customers. As a result, the only staff left is Sara with her daughter Sana, who works there as a part-time barkeeper, has a very small selection of basic drinks like beer and wine and a small number of regulars. Located directly above the bar is a small apartment unit, where Sara, and previously Sana, live. Featuring Sara and Sana's old bedroom, it also has a combination living room/kitchen. It was originally sparsely decorated until undergoing a refurbishment sometime prior to the year.
