While surprised by the differences from his previous world, Touya is growing accustomed to living in the new world with his smartphone. Together, he, Elze, and Linze accept a mission to head to the Royal Capital.
Along the way they encounter a young samurai, Yae, who dropped all of her travel coins, a currency in the new world. After treating Yae to sate her hunger, Touya grows worried about his own savings due to how much she eats. Afterward Yae joins their party to repay the favor, and their traveling group encounters Sushie, heiress to a duchy, under attack.
so few know exactly what 
kinds of Null Magic exist.
لذا هنالك قلّة ممّن يعرفون
أنواع السّحر الصفريّ تماماً

welche Zauber es so gibt.
y pocos saben exactamente
qué tipos de magia neutra hay.
y pocos saben exactamente
de qué tipos la hay.
donc on ne peut pas savoir

e quindi sono davvero in pochi 
a conoscerne davvero le varie tipologie.
então poucos sabem quantos tipos 
de magias não-elementais existem.
так что толком неизвестно,
сколько всего видов магии пустоты бывает.
