A Finishing Blow for This Enraged Growth Chimera! (この怒り狂ったグロウキメラにトドメの一撃を!, Kono Ikarikurutta Gurou Kimera ni Todome no Ichigeki wo!) is the fifty-second chapter of the KonoSuba manga series, and covers Chapter 5 in Volume 5 of the light novels.
As the villagers cheer Yunyun making her Crimson Magic Clan style introduction while Kazuma fears for her feelings afterwards, Sylvia attacks the chief's daughter who draws her away until cornered. Bukkororii and Soketto though Teleports to her side before Teleporting away together, making Sylvia thunder in rage.
Taking advantage of Sylvia's distraction, Kazuma sets his sights on the Growth Chimera, yet discovers that even with Aqua's magical power infused into it, the Railgun just won't operate. He and his companions are subsequently discovered by Sylvia, forcing them to flee while lugging the heavy rifle along. Sylvia proceeds to declare how she will hunt down every one of the Crimson Magic Clan cowards, at which Komekko stops to rebuke her by citing how powerful Megumin is.
Megumin accordingly steps up to introduce herself humbly, then against the protests of Kazuma whom she figured out had unlocked the storage door, casts Explosion at Sylvia, though the power is instead absorbed by the Railgun till it is filled to capacity and becomes operational. Kazuma immediately aims the weapon that can withstand one single shot at Sylvia, only for its trigger to be pulled by Komekko.
