Name: Sumire Motiki
Gender: Female

Occupation: Sanity Anchor, Sleeper operator
Affiliation: Vera Squad
Voice actor: Kaede Hondo
Sumire Motiki is a former underground idol who ends up bound for Antarctica after her aptitude as a Sanity Anchor is discovered.
Although she is not a frontline fighter, she plays a support role for investigators exploring the underground world known as Asylum.
At first, her goal is far from noble.
She wants to solve Randolph Syndrome, become a hero, raise her profile, and return to stardom as a top celebrity.
Because of that ambition, she is frustrated that she cannot serve as a combatant.
Her lack of resistance to Asylum prevents her from taking a battle role, which leaves her deeply dissatisfied with being support staff.
Sumire's motives may be selfish, but she is also hardworking and intelligent.
That mix makes her more than just an opportunist, giving her a sharp and determined edge.
In the early part of the anime, she keeps her distance from the rest of the squad.
She is especially harsh toward the new recruit, Daniel Shigure Kai.
Part of that hostility comes from jealousy.
Daniel joins with his own dream of becoming a hero and even manages to achieve decent results in his first mission, which stings Sumire given her own blocked ambitions.
As she gradually opens up, her tone becomes much more casual and natural.
She also grows closer to the other members of the squad.
Before joining the unit, Sumire worked as an underground idol and appears to have enjoyed a fair amount of popularity.
Her career took a dark turn when her agency deceived her and tried to push her into appearing in adult videos.
In the manga Asylum Side Story, the agency president falls into a coma due to Randolph Syndrome, allowing her to escape before signing the contract.
In the anime, however, the implication is darker, as Sumire worries that footage may already exist and be circulating.
She becomes especially upset when people bring up the provocative image videos she released in the past.
This is one of the clearest sore spots in her history.
Sumire's parents are both doctors.
They wanted her to become a doctor as well.
Because she chose a different path, she was disowned by them.
That family conflict adds another layer to her determination to succeed on her own terms.
Sumire serves as a member of Vera Rustamova's squad and acts as the operator for Sleepers investigating Asylum.
Her early dream is to use the mission against Randolph Syndrome as a shortcut back into fame.
Her attitude toward Daniel Shigure Kai begins to soften after he praises her refusal to give up on returning to idol life.
Even without knowing every detail of her past, he recognizes the strength in her persistence.
That moment becomes a turning point for her.
From then on, she starts acting less guarded and forms warmer bonds with the team.
