Kasumi Miwa

Biodata

Power Progression

Background and History

At seventeen, Miwa was a Kyoto Jujutsu High student who lacked a Cursed Technique. During the Shibuya Incident, she made a Binding Vow never to swing a sword again in exchange for a desperate attack on Kenjaku; the strike failed to break his skin 174 183 269.

After Sukuna’s defeat in the original Shinjuku Showdown, Miwa wished she could return to the battle and fight alongside her companions. She woke at a strategy meeting on November 20, before the showdown. Akuta, a sorcerer possessing her as a Cursed Object, explained that he had brought her consciousness back to give her that chance 174 175 177.

Appearance

Miwa has long blue hair. While Akuta resides in her, a second mouth can appear on her face, allowing him to speak 176 231.

Personality

Miwa often calls herself “useless Miwa,” but wants to be strong enough to protect and fight beside her companions. She fears formidable opponents and initially begs Akuta to undo her return, yet ultimately accepts the challenge because she no longer wants to remain a bystander 174 177 179.

Her confidence grows through harsh training and repeated battles. Although she celebrates her victories enthusiastically, she recognizes how much she owes Akuta’s support and values moments when she succeeds through her own skill 211 221 225.

Abilities and Skills

New Shadow Style and Simple Domain

Miwa is a swordswoman who uses New Shadow Style rather than an innate Cursed Technique 174.

• Simple Domain: Can neutralize an enemy domain’s sure-hit effect. Her stationary version originally covered a radius of 2.21 meters 185.
• Automatic counter: A Binding Vow not to move lets her reflexively attack anything entering that area. If both feet leave their starting positions, the domain and counter disappear 185.
• Batto: Reinforces and accelerates her sword draw. Kashimo nevertheless redirected the counter and disarmed her 185 186.
• Continuous Batto: Repeated draws produced slashes that countered Sukuna’s Grid Slash and wounded him 227.

Binding Vows

Miwa learns to use Binding Vows as combat tools under Akuta’s instruction 188 189.

• Her vow against swinging a sword was circumvented by removing the guard: by Miwa’s definition, the resulting weapon was no longer a sword 183.
• Thunderclap and Flash uses Binding Vows to turn her sword draw into a rapid advance, but its straight-line movement can leave her unable to dodge once triggered 190 217.

Thunderclap and Flash

A high-speed draw attack developed from Batto. Its large Simple Domain and speed demand immense Cursed Energy, which Miwa receives from Akuta 190 211.

• During training, she dashed nearly one hundred meters and cut a wooden target 190.
• She split Kenjaku’s Maximum: Uzumaki with the technique 217.
• Thunderclap Black Flash: She combined the charge with Black Flash against Mahoraga, shattering its Sword of Extermination on contact 232.

Black Flash

Miwa trained to understand the timing between Cursed Energy and a physical strike, though she initially could not land a Black Flash herself 193.

• She defeated Kenjaku with nine consecutive Black Flashes, later acknowledging Akuta’s Cursed Energy and secret help in using them 219 225.
• Against Sukuna, she independently landed a Black Flash with her sword 225.
• With Akuta’s guidance, Black Flash: Getsuga Tensho grazed Sukuna, destroyed much of his body and collapsed Malevolent Shrine 226.

Getsuga Tensho

A ranged crescent of compressed Cursed Energy fired through a sword. Akuta demonstrated the attack using Binding Vows while controlling Miwa’s body 214 215.

• Miwa later used it to intercept Sukuna’s Dismantle attacks 226.
• The technique requires a sword as its medium and consumes additional Cursed Energy 215 222.

Equipment

• Guardless borrowed sword — Kusakabe’s sword, modified by Akuta so Miwa could wield it without violating her Binding Vow 183.
• Repaired sword — Miwa’s Shibuya weapon, later broken by Kenjaku during their rematch 217.
• Black-sheathed uchigatana — A sword she selected from the Zenin Clan storehouse for its natural feel; she removed its guard before using it 223.

Relationships

• Akuta — A sorcerer residing in Miwa as a Cursed Object. He supplies Cursed Energy, training and combat guidance while insisting that she fight for herself; Miwa calls him the person she trusts most 179 181 235.
• Momo Nishimiya — Miwa’s close friend and classmate. Momo worries about her safety, helps her train and sees her off when she leaves Jujutsu High 176 190 208.
• Atsuya Kusakabe — A teacher and fellow New Shadow Style practitioner who lends Miwa a sword and spars with her 183 190.
• Kenjaku — His effortless defense against her Shibuya sword strike becomes a source of lasting shame. Miwa later defeats him and learns Sukuna’s location from him 174 219.
• Sukuna — The opponent Miwa wishes to fight. After a fatal first encounter and another return to the past, she defeats him at the Zenin Clan estate 174 204 206 233.
• Satoru Gojo — Miwa wants to prevent his death in the original showdown. After her victory over Sukuna, he summons her and Akuta to Jujutsu High 191 233.
• Yuta Okkotsu — Miwa recounts the original showdown to him so he can prepare to prevent Gojo’s death 190 191.

Story Role and Major Arcs

First Return and the Shinjuku Fight

Miwa reveals her intent to fight Sukuna alongside Jujutsu High, then tests her abilities against Hajime Kashimo. Her automatic counter blocks his first attack, but he disarms her. She trains with Akuta, Momo and Kusakabe before entering the Shinjuku battle 180 186 190 200.

Akuta protects and heals Miwa during the fight, but Sukuna ultimately cuts her in half with a Space Slash. She returns again to November 20 202 204 206.

Training and Kenjaku’s Defeat

On her second return, Miwa leaves Jujutsu High to find Sukuna ahead of the planned showdown. Akuta subjects her to repeated simulated deaths in his Innate Domain, improving her reactions and combat intuition without injuring her real body 206 208 211.

Searching for Sukuna through Kenjaku, Miwa confronts and defeats the man who had once stopped her strongest sword strike. Kenjaku reveals that Sukuna is at the Zenin Clan estate 212 216 219.

Battle at the Zenin Clan Estate

Miwa finds a replacement sword at the estate and challenges Sukuna. With Akuta’s support, she survives Malevolent Shrine, cuts down Mahoraga and defeats Sukuna. Gojo later reveals that Sukuna survived by returning to Yuji Itadori’s body as a Cursed Object 223 226 232 233.
