Toaru Kagaku no Railgun Manga Chapter 050

"The Battle Begins" (開戦) is the 50th chapter of the Toaru Kagaku no Railgun manga series.

Synopsis
Kongou Mitsuko continues her solo investigation on the disappearance of Misaka Mikoto's "sister" (i.e., Misaka 10032). As she traces the last steps of Mikoto's "sister", she tries to gather the information she had, and wonders why Misaki transported the sister with a vehicle instead of simply controlling her into going to the place she wanted. She soon arrives at an alleyway where 10032 was taken, and upon finding the Gekota mask that Mikoto likes, she hears the sounds of dogs barking elsewhere. Upon following the barking sounds, she sees two stray dogs surrounding a small black cat. Kongou assumed that the dogs are bullying the cat, so she tries to shoo them away, although Kongou ends up being chased by the dogs.

After a long chase, Kongou manages to lose the dogs, although she ended up tired because of this. Now, Kongou finds herself with a stray cat that needs its owner, so she decides to look for a member of Judgment to give the cat to. In her search for someone from Judgment, she stumbles upon her friend Wannai Kinuho. Kinuho recognises the cat as the one entrusted to her by Mikoto's "sister". Meanwhile, Kongou tries to explain what is going on, and although Wannai doesn't quite grasp the situation, she decides to keep the cat while she looks for a Psychometrist friend who can help out.

Meanwhile, a robotic dog is seen roaming District 7. It turns out that it is under Baba Yoshio's control, and he is using it to find some clues on what is going on outside. There, he catches the conversation between Kongou and Wannai. His attention is shifted to their small chat, and the word "sister".

Wannai soon discovers that she left her phone back in the School Garden's lockers and decides to look for it first. Meanwhile, the cat remains in Kongou's care as she decides to continue looking for clues. While she fantasises about becoming a hero in the eyes of Mikoto, Baba approaches her. He requests for a private talk about Misaka Mikoto's sister.

Nearby, Saten Ruiko visits a souvenir shop and finds a limited-edition Gekota keychain for the Daihaseisai. She thinks that someone would be interested in having one — or in fact, already knows about this — but for some reason, she can't pinpoint who that particular someone is. Then, as she tries to think who that person is, she sees Kongou with someone unfamiliar.

Baba is somewhat curious if Misaka's sister is in fact her true sister or someone else entirely. He decides to drop that topic and tells Kongou that he is here to shelter Mikoto's sister, and he wanted to get some information about her. Kongou is hesitant to work with Baba, so he decides to obtain the information from her... by force. Kongou soon finds herself surrounded by more than ten of Baba's robotic dogs. As she asks the cat on her hands to seek refuge, she faces the robot army on her own. Kongou soon thinks that holding back the information she has was a good decision as she was very suspicious of Baba from the start, although she is disappointed that she cannot use him to get information on Misaki. With no other options, she prepares to fight.

Elsewhere, Mikoto is stuck mingling with Misaki's clique and is desperate in looking for a way to get away from them. Soon, she gets her chance when a girl lets go of her balloon; using her powers, she reaches an overpass where trains travel along and catches the balloon just in time to hitch a ride on the train. Mikoto manages to get away from the range of the telepath Kobayashi Satori, but two others from the clique catch up to the train, much to Mikoto's disappointment.

Kongou struggles to avoid the relentless assault by Baba's robots. Because of the lack of nearby objects to use, her Aero Hand ability appears to be ineffective on the current battlefield, which is completely flat. Baba confidently requests Kongou to back down and cooperate with him. However, an enormous shockwave suddenly whips through Baba's robotic army, tossing them into the air. As Kongou prepares a counterattack, she tells Baba that his analysis of her ability was insufficient. One, she can use her abilities even on the ground; and two, her output can launch a radio tower into the stratosphere using multiple ejection points. At that moment, Baba thinks that he has severely underestimated Kongou's damage output. However, upon glancing at the cat Kongou has with her, Baba appears to have discovered his trump card.

Meanwhile, Wannai, joined by her friend Awatsuki Maaya, finally finds their Psychometrist classmate, although Kongou is no longer there. Saten stumbles upon them and Wannai decides to ask if she has seen Kongou. Ruiko has seen Kongou, but she does not know that she is currently facing a battle on her own... and that she has just been defeated.

Baba gloats about his victory, which he achieved by targeting the cat and using his robotic mosquito to paralyse the distracted Kongou. He tells her that Misaka Mikoto must be a horrible person for making someone do this for her. Kongou tries to defend Mikoto despite her condition, but she is helpless against Baba's attacks against her. Until the last moment, Kongou keeps her arms around Misaka's cat. Baba decides to stop attacking Kongou upon remembering that he needs her alive and orders one of his dogs to retrieve her. However, Maaya and Kinuho arrive at the scene, who both learned of Kongou's whereabouts with the help of Saten, who also joins them. As Saten protests about what Baba did to Kongou, Baba taunts the girls and tell them about Kongou being second rate because of following the requests of other people. Although powerless, Saten becomes angry. However, her anger cannot compare to the feelings that Awatsuki Maaya and Wannai Kinuho are feeling at the moment. Kinuho and Maaya ask Saten to watch over Kongou and the cat while the two of them prepare to fight Baba.
