Did I read it right, was that a "Thermite Incendiary Bomb"? It made me feel like there were a couple of things missing on the next page, like fire, damage, death and a sarcastic comment by the translator
Sooooo, the author just introduced a new villain and new characters which were supposed to be the nemesis of the heroines and now he will finish all of that in just 3 chapters... weird. Anyway thanks for the cap
