Story in Touhou[]
Urban Legend in Limbo Sumireko is the main antagonist of Urban Legend in Limbo and the final boss in most of the characters' scenarios in story mode. Sumireko manages to go through the Great Hakurei Barrier by using the Occult Balls, which are special stones gathered from Mystery Spots in the Outside World. However, after a short period, she is suddenly ejected from Gensokyo. Learning from this, Sumireko starts with brief excursions into Gensokyo to learn more about it, appearing to anyone who catches sight of her as an ominous black shadow. Sumireko soon devises a plan to spread rumors of the Occult Ball's powers and scatters them around Gensokyo for its residents to find. Once the balls are gathered, they warp back to the Outside World along with whoever gathered them all, just for enough time for Sumireko to learn about them before they are transported back. She then re-enters Gensokyo and scatters the balls again, thus beginning the incident of Urban Legend in Limbo. Her plan works for a while, and although she is baffled at why everyone who comes out of Gensokyo ends up fighting her, she enjoys it nonetheless. Soon enough, Mamizou Futatsuiwa is made aware of the incident and devises her own plan: she claims to have Gensokyo's own Occult Ball in her possession when challenging Sumireko, claiming it would allow her limitless travel between Gensokyo and the Outside World. Mamizou instead tricks Sumireko into entering Gensokyo the proper way, which does let her stay there, but as Sumireko does not know how to get back out, she is trapped in Gensokyo. in Sumireko's story mode in Urban Legend in Limbo follows her as she is trapped in Gensokyo, whose residents attempt to scare her to teach her a lesson. In the end, she is confronted by Toyosatomimi no Miko, who reminds Sumireko that she can use the Occult Balls to escape Gensokyo temporarily. She returns to the Outside World, and believing she will eventually be killed by the youkai of Gensokyo, she decides that when her time in the Outside World runs out, she will sacrifice herself to, purportedly, unleash the full power of the Occult Balls and destroy the Great Hakurei Barrier. Before being brought back to Gensokyo, she is confronted by Reimu in her own story mode, who realized that one of Sumireko's Occult Balls was swapped for a Lunar Capital ball, which if activated would link Gensokyo with the Lunar Capital instead. Although Reimu defeats Sumireko and saves the Great Hakurei Barrier, the Lunar Capital ball was activated, setting up the events of Legacy of Lunatic Kingdom. Upon returning to Gensokyo, Sumireko is detained by Reimu, Mamizou and Kasen Ibaraki. Deciding Sumireko was no longer a threat, they return her to the Outside World through the proper method. A few days later, Sumireko reappears at the Hakurei Shrine, as she had discovered that ever since leaving Gensokyo, she could travel back there in her dreams. No longer antagonistic, she befriends Gensokyo's residents in earnest, and her tales of the Outside World turn her into a brief celebrity.
Antinomy of Common Flowers
Sumireko is a playable character with an unlockable story mode in Antinomy of Common Flowers. In her story mode, she visited Gensokyo at a bad time as the Dream World has been thrown into chaos by the Yorigami Sisters' incident, and she ends up trapped there as a result. She teams up with Doremy Sweet to traverse through the Dream World and reach Gensokyo, whereupon they are tasked by Yukari Yakumo to dispatch Sumireko's own Dream Soul that has been released into the Outside World by the incident. Curiously Sumireko somehow encounters two of her own Dream Souls, but defeats them with Doremy's help. She awakes in the Outside World afterward, greeted by Doremy to confirm that she is the real Sumireko.
Violet Detecor
Sumireko is the main protagonist of Violet Detector. For some time, she has been having the same weird dream, in which she is constantly attacked by the residents of the dream world for no reason. She finally discovers that the dream dwellers hold a grudge against her for having a flesh body allowing her to go in the real world, and Doremy Sweet tells her that she can only expect the situation to worsen. After some time, she encounters and fight against Okina Matara. Okina is impressed by Sumireko who has been able to fend off the dream dwellers for quite some time. She offers her some help, in order to make the dream dwellers recognize her strength and make them stop attacking her. But in order to achieve that, she has to defeat even more powerful nightmares, so Okina lends Sumireko some powers on top of her psychic abilities, allowing her to cheat death in certain situations. Sumireko then goes on and fights powerful nightmares, in the form of strong dream dwellers teaming up against her. After a week of fighting, she encounters another Sumireko. During that confrontation, she realizes that she was actually the Dream Soul of the real Sumireko, the other one, who is trying to get her body back. But at this point, Dream Sumireko has become stronger than the real Sumireko and is able to defeat her. Okina, not willing to take any side in the confrontation between the two Sumirekos, decides to take back the power she lent Dream Sumireko to make things fair. The real Sumireko challenges her dream self once again and eventually defeats her. The next day, Sumireko wakes up in the real world as if nothing happened, having no recollection of what transpired in her mind. She stopped having those nightmares, but the photos of danmaku battles still lie in the memory of her smartphone.

After Reimu Hakurei tried to defend Sumireko, the bubble pops on Reimu's gohei and Reimu collapses and starts sleeping. Sumireko realizes that Marisa Kirisame did the same. Kasen Ibara appears and, after Sumireko explains the situation, she thinks they are dream souls with the dreams Sumireko had to had instead of her traveling to Gensokyo. As a result, Marisa had a dream where she was in Sumireko's school. However, Marisa's dream ended up in Reimu's.

Relationships[]
Reimu Hakurei & Marisa Kirisame
In Urban Legend in Limbo and Curiosities of Lotus Asia, Reimu and Marisa are frequently seen doting on her, making sure she's safe and trying to keep her from getting into trouble. In an interview with Aya Shameimaru in Alternative Facts in Eastern Utopia, Sumireko refers to both Reimu and Marisa as friends she's made since coming to Gensokyo. Reimu admits that although she's worried about Sumireko's appearance in Gensokyo and its implications for more Outside World humans passing through the barrier, Sumireko has made things "fun" in Gensokyo again. Marisa also tries to give advice on how to talk to the local residents. In Violet Detector, Sumireko refers to both of them with friendly informal names like "Reimu-cchi" and "Marisa-cchi," typically used between close friends.
Rinnosuke Morichika
In Curiosities of Lotus Asia, which is primarily told through Rinnosuke's perspective, Rinnosuke and Sumireko often talk about the Outside World and the various items that filter in through the Great Hakurei Barrier. Rinnosuke shows a great deal of care towards Sumireko, worrying about her safety, while Sumireko seems to regard him as a nag, and goes so far as to criticize him for his habits, such as smoking cigarettes. Despite that, they seem to be good friends, with Sumireko recently beginning to work as a "part-timer" at Kourindou. Mamizou Futatsuiwa
In Alternative Facts in Eastern Utopia, Sumireko mentions that Mamizou often visits her in the Outside World. The exact details of this aren't known, but Sumireko implies that they're friends, and that Sumireko respects her as an elder.
Kasen Ibaraki
In Alternative Facts in Eastern Utopia, Sumireko mentions that her and Kasen are also friends, and says that they hang out a lot in Gensokyo, calling her "Kasen-chan." or "Kasseny" In Urban Legend in Limbo, Kasen expresses resentment that Sumireko views youkai with such a casual and playful attitude, feeling that Sumireko should show youkai more respect. Despite that, it's shown in Wild and Horned Hermit that Kasen has grown a bit softer on her in more recent times.
Fujiwara no Mokou
Initially annoyed by Sumireko, Mokou challenged Sumireko to a duel. The two were able to match each other's strength. Mokou extended an invitation to have a rematch sometime in the future, admiring the young girl's fighting spirit and passion, and thanking her for giving her a tough challenge. After fighting again, Mokou helped Sumireko getting out of the Bamboo Forest of the Lost. It appears the two have become friendly rivals.
In Antimony of Common Flowers, Doremy teams up with Sumireko. During the incident, Sumireko is faced with fighting both her dream-self and her occult doppelganger, who have also teamed up to take down the "real" Sumireko.
