However, he finds himself hospitalized after sustaining injuries coming to the rescue of Last Order. One night while in the hospital he encounters a magician named Estelle Rosenthal and learns of a plot by the shadowy organization DA using the sisters that begins with Last Order. Before long, he finds himself caught in the middle of a conspiracy involving dangerous organizations as he fights to protect Last Order and Academy City.

The opening and ending theme songs will be performed by THE SIXTH LIE and Sajou no Hana, respectively. The anime will premiere in Japan on AT-X, Tokyo MX, MBS, and BS11 in July 2019.


Accelerator (Voiced by: Nobuhiko Okamoto)

Out of the seven Level 5 Espers in Academy City, Accelerator is regarded as the most powerful. He possesses an ability that allows him to manipulate the vector values of anything he touches, which has innumerable uses. This ability also reflects ultraviolet rays, which is why he appears albino with his pale skin, white hair, and red eyes. Accelerator has actively participated in questionable experiments with the sole mission of creating the very first Level 6 Esper.

Last Order / Misaka 20001 (Voiced by: Rina Hidaka)

Last Order is the administrator of the Misaka Network and the fail-safe in case the sisters go out of control. Unlike the other sisters, she can show emotions and has a close relationship with Mikoto, Misaka, and Accelerator.

Touma Kamijo (Voiced by: Atsushi Abe)

A high school senior in Academy City, Touma comes across as more ordinary than his peers. He is considered a Level 0 Esper; but despite this, he possesses an unusual power in his right hand called “Imagine Breaker,” which cancels out both supernatural abilities and his own luck. He is skilled at street fighting, and when it comes to a crisis, he has impeccable judgement and is incredibly decisive. Because of his strong sense of justice, he also cannot stand abandoning those in need. He strives to live a normal life, but is usually caught up in the messes of both the magic and science communities.

Index Librorum Prohibitorum (Voiced by: Yuka Iguchi)

A sister of Necessarius, the Church of Necessary Evil, Index is small in stature with a baby face, white hair, and blue eyes. Because of her photographic memory, Index has the contents of 103,000 grimoires memorized, which grants her immense and highly sought-after knowledge. Her white robes, which have special gold embroidery, prevent harm from coming to her. She’s nicknamed “Hungry Sister” because she is in love with eating and seems to always feel hungry. Among other topics, Index is skilled when it comes to different languages, but she’s utterly hopeless when it comes to science, especially as it pertains to machinery.

Mikoto Misaka (Voiced by: Rina Satou)

The daughter of a rich family, Mikoto is a 14 year old who resides in Academy City. Out of the seven Level 5 Espers in the area, she ranks third amongst them. Able to freely manipulate electricity and electromagnetism, she also has a trademark move that involves flinging metal objects at deadly speeds, which is how she got her nickname “Railgun.” Not your average rich girl, she has a rough and brash personality. Though she does come across as a tomboy, she also has a secret fondness for fancy things and cute clothing.

Shiage Hamazura (Voiced by: Satoshi Hino)

The former leader of a group of Level 0 Espers called Skill-Out, Shiage left the group after failing a mission that involved being defeated by Touma and Accelerator. He is now the chauffeur of Team ITEM, though his jack-of-all-trades status allows him to work other small jobs for them that can include everything from lock-picking to forging documents. Despite this, he doesn’t put much stock into what he can accomplish, and has an obvious inferiority complex.

Estelle Rosenthal (Voiced by: Yurika Kubo)

Estelle is a necromancer trying to stop the rouge Anti-Skill group DA from capturing Last Order.
