Lv2からチートだった元勇者候補のまったり異世界ライフ [Lv2 kara Cheat datta Moto Yuusha Kouho no Mattari Isekai Life] #12

Volume 12 of this beloved isekai series arrives in festive style, with the cover showcasing a lively celebration scene — a cheerful young woman in an elegant kimono takes center stage, holding a decorative fan, while fireworks burst brilliantly in the night sky behind her. Companions dressed in equally colorful traditional attire join her, lanterns and festival décor framing the warm, joyful gathering. It's a delightful snapshot of the "mattari" (easygoing) spirit that defines this series, promising another relaxed yet charming volume of otherworldly slice-of-life adventure.
