Hoshino Ichika: Childhood friends and bandmates. Back when Saki was in the hospital, Ichika would visit her the most often, aside from close family members. Ichika enjoys Saki's happy demeanor and persistent smile, saying that she is good at cheering people up, while Saki is glad Ichika is always there for her. Ichika often worries for Saki's wellbeing, while Saki tries to assure her that she has nothing to worry about. Despite their status as close friends, the two had a bitter argument in Parallel Harmonies, where they had to write Leo/need's debut song together, but eventually reached a resolution thanks to the VIRTUAL SINGERs in SEKAI.
Mochizuki Honami: Childhood friends and bandmates. They had lost touch due to Saki's hospitalization, but have since reunited. Saki always tries to make her smile with hugs and apple pies. The two are often the ones in the group who radiate positivity, as they both share the same aspiration to make the people around them smile.
Hinomori Shiho: Childhood friends and bandmates. Their relationship was once strained, but they have since reunited and become closer. Saki thinks Shiho can be too strict, but admires her skills as a musician and enjoys being praised by her.
Hanasato Minori: The two were coworkers at carino/carina, until during STEP by STEP! when Minori resigned to focus more on idol activities.
Kiritani Haruka: Classmates from 1-C and friends following the Run! Sports Festival! Committee Rush event. The two were both members of the Sports Festival Committee.
Momoi Airi: Saki is a big fan of Airi and often spent her time watching variety shows featuring Airi while she was hospitalized. When she ran into Airi at school, she instantly asked for an autograph and a handshake. In Secret ♡ Operation Valentine's Day, the two teamed up with Emu to form a secret alliance and make Valentines Day chocolates together, with Saki gushing over Airi all the while.
Hinomori Shizuku: Shiho's older sister. Saki and Shizuku came to know each other through Shiho, and have now become good friends. Saki sees Shizuku as a great older sister, to the extent that she wants an older sister of her own specifically because of Shizuku.[1]
Azusawa Kohane: Friends following the The BEST Summer Ever! event.
Aoyagi Toya: A childhood friend of both the Tenma siblings, as their parents knew each other through playing piano. He often passes on the plushies he wins from the arcade to Tsukasa to give to Saki, as he can't bring them home for fear his father will be upset. He still worries about Saki's condition, and asks about her health when hanging out with Saki and Tsukasa after school.[2]
She is one of the few characters whom Toya refers to by their first name, as he calls her "Saki-san", likely because of their childhood friend status. Despite this, Saki and Toya aren't shown to be as close to each other as Tsukasa and Toya are, with this likely being due to her frequent hospitalization during her childhood.
Tenma Tsukasa: Saki's older brother. Tsukasa is shown to have taken care of her during the times when she was sick. He wanted Saki and her childhood friends to be together again, since he partly blamed himself for not preventing their falling out. Tsukasa is often showing off in front of Saki and the others, which ends in chaos, much to Saki's embarrassment. Despite this, Tsukasa works hard to protect her friendship so she can live a normal high school life. Tsukasa is often overprotective of her, being worried whenever anything about her seems off, which annoys Saki, but she understands he's trying his best. Saki admires him greatly.
Otori Emu: Classmates from 2-B and good friends. The two participated in the Miyamasuzaka Sports Festival and were on the committee together. They quickly got along as they shared the same enthusiasm for how fun the sports festival can be. When they first met, Saki commented on how Emu reminded her of Tsukasa, unaware at the time that they are in the same theatre troupe.
Yoisaki Kanade: Saki learned of Kanade through Ichika and Honami, and the two eventually met in the Relaxing Tea Time event. They became better friends in Show your shine after having tea together.
Asahina Mafuyu: Saki's upperclassman. The two have interacted a few times, and in the Bubbles of Solace side story, Mafuyu plays with a bubble blower given by Saki, even though she thought bubble blowers aren't for high schoolers.
Mafuyu is one of the two characters whom Saki calls by their last name.
Shinonome Ena: First met in Relaxing Tea Time. Saki admires Ena's art, and tells her that she enjoys watching N25's videos.
Ena is one of the two characters whom Saki calls by their last name.
Akiyama Mizuki: Friends following the Bustling Cafe ●REC! event, during which the two work together to make orders in the cafe. Though they initially bond over both knowing Tsukasa, they ultimately befriend one another due to their similarly energetic and passionate personalities. They also both tend to obsess over tiny details, which is revealed when Saki insists Mizuki remake an order of waffles because the whipped cream fell apart slightly. Mizuki relates this to their own experiences animating videos and comes to respect Saki more for the care she puts into her work.[3]
Hatsune Miku: Virtual Singer and friend.
Kagamine Rin: Virtual Singer and friend. They are similar in terms of personalities, to the point where Shiho mentions that "It's almost like there's two of Saki now".[4]
Kagamine Len: Virtual Singer and friend.
Megurine Luka: Virtual Singer and friend.
MEIKO: Virtual Singer and friend.
KAITO: Virtual Singer and friend.
