"August 19, Part 1" (八月十九日① Hachi-gatsu Jū-ku-nichi ①?) is the 26th chapter of the Toaru Kagaku no Railgun manga series, released on November 27, 2009.
The chapter opens with ITEM receiving a debrief of their mission from their liaison: there is a high probability that an Electromaster is going to attack one of the facilities and they have to stop the attack. Kinuhata Saiai suggests attacking the suspected attacker first, but the liaison explains that the client's orders don't allow this. Frenda Seivelun then prepares her explosive toys in the air vents of one of the two facilities. She hears a noise and realises the attacker has arrived.
Misaka Mikoto rushes into a large room and above her, Frenda's toys detonate, making the ceiling on top of her. Mikoto redirects the debris with magnetism, but Frenda quickly follows up by igniting her fuselines to detonate more toys. Mikoto uses debris as shields, but one piece of debris has a bomb hidden inside it. Mikoto still manages to avoid the explosions and, upon following Frenda's fuse-lines, deduces where she is. She pursues Frenda around a corner and another toy explodes, sending ceramic shrapnel at her, but Mikoto is able to disintegrate the ceramic using electricity. Mikoto chases Frenda up a staircase while declaring that she won't forgive anyone who assists the experiments. Frenda pretends to be scared but instead destroys the staircase. However, Mikoto is able to use her magnetism to reconstruct it.
The chapter ends with Mikoto chasing Frenda into a large room, seemingly cornering her.
