Spoiler warning!
This article contains plot details about an upcoming episode.

Tajima Yoriko is one of the story's main characters. She heavily bullied Alice in the beginning and almost gets killed for it, but winds up letting Alice live in her apartment to fend off the Organization assassins.

Yoriko acts grumpy and no-nonsense most of the time. She starts out as a horrible bully who constantly picks on Alice, but ends up growing closer to her once all the trouble with the Organization starts. She disliked Alice for being weak-willed and gave her no pity about her miserable life, but was willing to respect her if Alice matured and learned to stand up for herself.

However, Yoriko was really being severely manipulative towards Alice, as she was frequently reading her mind and acting accordingly to become like family to the affection-starved spider girl in a matter of weeks.

Yoriko's been alive for a century and has been responsible for countless deaths as the secret leader behind Japan, so the lives of others are playthings to her. She's able to calmly talk about how she's come to admire Alice in the same breath she admits being responsible for the ruin of Alice's family and attempts to kill her for being a loose end in her master plan.

Abilities Edit

She's a normal girl with no fighting abilities.

Or so it seemed. As the Organization's Boss, "Nejirebane", Yoriko is themed after the Strepsiptera insects, who are also known as twisted-wing parasites.

She has the ability to read minds and can control the actions of strong-willed people who accept to become "Suzumebachi" and follow her orders, albeit only one at a time.

Like Imomushi, Yoriko is immune to chemicals and even Sasori's red toxin only causes her to fall into a suspended animation state for a while.

She was born early in the 20th century and her physical appearance didn't age past 6 for most of it. Eventually, however, she found herself unable to completely control a Suzumebachi's will and her body suddenly aged to a 15-years old appearance. Yoriko believes she can only cast her spell on one more person before she turns into an ordinary girl.


Past Edit

The girl who is known as "Yoriko" was born early in the 20th century and was found to inexplicably be unable to age beyond age 6. After enduring some harsh treatment from her parents, Yoriko realized she could brainwash and control her father's actions. When her mother realized this, Yoriko got rid of them both. She started experimenting with the conditions of her abilities and using one person after another until she ended up controlling Japan's government with Hideki Tojo as her puppet.

After getting the country nuked on purpose at the end of the Second World War, Yoriko adopted an orphaned boy called Masashi Ushijima and named herself after his late mother. The two established the Organization and united all sorts of assassins under their command until Masashi had to be replaced as well.

On top of feeling somewhat bad for discarding a wasp she actually cared for, Yoriko realizes her abilities are failing her. She's unable to completely control Jin Togawa and her body begins aging again. At this point she develops an interest on Jin's daughter Alice and goes to the same school as her...


Yoriko is first introduced as a bully who tormented Alice with her friends Kawanishi and Muraoka. Unbeknownst to her, Alice undergoes her assassin training from Kumo, so when Yoriko next harasses Alice, she almost gets her head shot off.

Yoriko tries to report Alice to the police, but is unable to due to the Organization's cleaners getting rid of all evidence. She becomes curious about Alice and winds up involved in her battle against Sasori. After this she lets Alice live at her home, so the homeless spider girl gets a roof over her head and Yoriko gets a bodyguard to protect her from the Organization.

After a while, Yoriko begins treating Alice more kindly, since Alice has been getting lots of injuries protecting her and the two have been through similar hardships. Yoriko tells Alice a kind person like her isn't much of a murderer anyway. This troubles Alice, as she does think of herself as a murderer and believes this to be a hurdle in befriending Yoriko and Oki.

During the Arachnid Hunt, Yoriko is repeatedly separated from Alice and has her life threatened numerous times, which culminates in Sasori suddenly stinging her with poison meant to cause instant death. She is thought to die, but reveals herself alive and well later to Alice, right after ordering Ginyanma to kill Suzumebachi. Yes, Yoriko is the leader of the Organization.

Alice is in disbelief at all this, so Yoriko explains that as an Strepsiptera person, she has such resistance to poison that even Sasori's red toxin only left her on a period of suspended animation. She can read Alice's thoughts and despite her looks is actually a century old. Yoriko is glad to have met Alice and promises to grant anything she wishes, but also has something to ask of her...

Yoriko explains her real background to Alice and demands she join her as the final Suzumebachi, but Alice refuses to let herself be controlled in any way. After Ginyanma gets killed trying to shoot Alice, Yoriko attempts to do the dirty work by herself, but Kabutomushi rushes in and blows her off the building. Just before Yoriko hits the ground, she remarks to a distraught Alice that deep down she did think of her as a friend after all.
