Itai no wa Iya nanode Bougyoryoku ni Kyokufuri Shitai to Omoimasu.

Synopsis

In the runup to the guild event, Sally notices Frederica of the Order of the Holy Sword guild scouting them and challenges her to a duel. After Sally manages to evade all of her magic attacks, Frederica surrenders and tells her about the Flame Emperors guild, unaware that the "skills" Sally used against her were fake. The guild competition soon begins, which each guild tasked with stealing orbs from other guilds while defending their own. Sally uses her stealth and cunning to gain a few orbs, having a brief brush-in with the Holy Sword's Dread before managing to steal an orb from the Flame Emperors. With several orbs under their control, Maple Tree take advantage of Maple's defense to defend their base from all attackers.
