In How NOT to Summon a Demon Lord (Manga) Vol. 19, the story unfolds against the backdrop of a looming threat posed by the Demon Overlord Modinaram, who endangers humanity. In response to this crisis, the protagonist, Diablo, realizes the urgency of enhancing his combat abilities. His journey begins with a visit to Faltra City, where he seeks vital information before embarking on a quest to the northern mountains, home to the Demon Lord's Domain.

Diablo's goal is to train under the esteemed swordmaster Graham, hoping to master his exceptional swordsmanship. However, upon arrival, he discovers an unexpected twist: the legendary swordmaster has been replaced by a young dwarf girl named Sasara, who assumed the role just six months prior. This revelation shifts Diablo's plans dramatically, as he must now navigate the challenges of becoming her disciple instead of the renowned master he initially sought.

The dynamics of their relationship promise to bring both comedic and heartfelt moments as Diablo learns to adapt to his new situation.
