Character Setting

Edit

Sitter Baby is a villain from the manga series Mashle who belongs to the criminal organization Innocent Zero and specializes in magic that turns opponents into helpless babies.

Sitter Baby is a member of Innocent Zero, a notorious criminal group in Mashle.

He attacks students at the Divine Visionary Examination site to scatter the Divine Visionaries and disrupt the exam.

He is a bizarre man who dresses in baby-like clothing, creating a creepy visual contrast with his cruelty.

Sitter Baby is a sadist who enjoys tormenting the weak and watching them suffer.

His magic focuses on transforming others into babies, stripping them of strength, magic, and dignity.

Despite his terrifying ability, he himself is physically fragile and avoids direct combat.

Name: Sitter Baby

Gender: Male

Affiliation: Innocent Zero

Occupation/Role: Villain, attacker during the Divine Visionary Candidate Selection Exam

Birthday: May 5

Age: 44

Height: 166 cm

Weight: 55 kg

Blood Type: A

Dominant Hand: Right

He appears much older than typical students but still infiltrates student settings within the story.

His childish costume contrasts with his middle-aged age, adding to the unsettling comedy of his character.

Baby’s Magic (Babies)

Sitter Baby uses a unique magic known as Babies, which transforms the target’s body into that of a baby.

He can activate this magic without raising his wand, allowing him to cast it unexpectedly and deceptively.

He often transforms himself into a baby to lure opponents into lowering their guard.

Once they relax, he chants the spell and turns them into babies in return.

When the magic is successfully cast, the target’s body becomes that of a baby, and their magical power is drastically weakened.

In addition, the target’s mind gradually regresses, becoming more and more like an infant, losing rational judgment and combat ability.

Although Babies is extremely powerful, it appears to have a trade-off: Sitter Baby’s own body is weak and fragile.

Because of this, he rarely fights directly and instead sends his subordinate monsters to attack his enemies for him.

Sitter Baby participates in the raid on the Divine Visionary Candidate Selection Exam together with Innocent Zero’s leader and other members.

Their goal is to cause chaos at the Divine Visionary Examination Site and force the Divine Visionaries to split up.

During the attack, Sitter Baby uses his Babies magic on Dot Barrett and Lance Crown.

He successfully transforms both of them into babies, weakening them physically and magically.

Even in their weakened state, Lance Crown manages to focus his remaining magic power and unleash a localized Graviol spell.

This gravity magic slams Sitter Baby literally into the ground, pinning him down and disrupting his concentration.

Because his spell is broken, the baby transformation placed on Dot Barrett and Lance Crown is canceled.

Sitter Baby is defeated not by raw power, but by Lance’s clever use of limited magic and timing.

Sitter Baby’s Babies magic resembles a common trope in fan works where characters are turned into babies.

As a result, there are many fan creations where characters are hit by this kind of spell even when Sitter Baby himself does not appear.

These fan works include both romantic and more niche-targeted interpretations, using the baby transformation as a plot device.

His power has therefore become a popular tool in fanfiction and fan art, independent of his screen time.

In the stage play adaptation of Mashle, Sitter Baby appears as a student of Valkis Magic School.

Given that he is canonically 44 years old, the idea of him being a student is humorously absurd and adds to his bizarre charm.
