After defeating Clayman at Walpurgis, Rimuru officially became a Demon Lord and a member of Octagram. Meanwhile Diablo awaits Rimuru's return in Tempest, and is anxious to learn about his master's activities as soon as possible. A look back at Walpurgis.
Miss Shion and Miss Treyni told me 
the story through their thoughts.
الآنسة شيون والآنسة تريني رويتا لي
الرّواية من خلال أفكارهما
J’ai déjà contacté dame Shion
et dame Tryney
Oh, la signorina Shion e la signorina Treiny
A Shion-dono e Treyni-dono também me contaram
a história por meio de seus pensamentos.
Я успел мысленно обсудить
случившееся с Сион и Трейни.
