Toaru Kagaku no Railgun Manga Chapter 139

Extraordinary (破格) is the first half of 139th chapter of the Toaru Kagaku no Railgun manga series, released on March 26th 2022 in Monthly Comic Dengeki Daioh. The second half was released on April 27th 2022.

The chapter was released in 2 parts when serialized in Dengeki Daioh and combined together when compiled for the tankōbon version.

Part 1
Mikoto's plan to only help Urui Aika once is foiled by additional attacks by the other members of the Hasekura Clique. Upon seeing the iron sand created to block an ice attack from one of the attackers, they quickly surmise that Mikoto is the hidden helper. As Mikoto finally reveals herself, one of the attackers introduces herself as Amano Ayane and steps forward to fight Mikoto, with a hidden desire to determine the strength of a Level 5. Despite not having the interest to fight anyone at the moment, Mikoto is pursued by Amano and her ability based on manipulating air pressure onto a wind turbine. Amano, however, quickly finds out that all that Mikoto has been doing is divert any attack coming her way.

Part 2
Failing to bring out Mikoto's full potential, Amano falls from the wind turbine. As Mikoto tries to catch up to Amano, one of the turbine blades hit by Amano's wind blades snaps and flies towards the other members of the Hasekura Clique. Mikoto manages to grab onto Amano and, for the first time in action, uses a coin as ammunition for a Railgun that is fired on the turbine blade, disintegrating it completely.

Upon landing safely with Amano, Mikoto reveals that the Railgun shot was a gamble, much to the surprise of everyone. Amano decides to leave, already impressed with what Mikoto had demonstrated. Meanwhile, although Urui is grateful for being rescued, she reminds Mikoto that the conflict should be resolved among the cliques involved.

As Mikoto is scolded by Kiyoshi for meddling with clique affairs (especially siding with the other clique), Yasutoba Suika is comforted by Hasekura Reiri who rushed back from her trip to Paris. Hasekura also checked up on the other members and she learned that very few people in the clique are talking about her successful demonstration in Paris and there is somehow an attempt to bring in more people to the clique, much to her chagrin. Another thing that she discovered is that Misaka Mikoto is now known as the "Railgun", after the shot that she unleashed to destroy a turbine blade.

Hasekura continues to check on the investigation on the incidents involving her clique and the Mikagami Clique. In particular, Enjou Kasumi is known not only for her short temper but also for not liking her short temper, and Kazan'in Tsukasa is known for her prejudice based on social class and is not the kind of person to lie about being overcome by someone like Enjou. Hasekura also discounts the Sha Clique as a culprit as she can't see the largest Tokiwadai clique to harm the school's reputation that way. In addition, she hears news of Lily (from the Sha Clique) confronting and failing to rein in Shokuhou Misaki. By coincidence, Shokuhou is nearby, giving her the opportunity to clarify things with her.

Trivia
