The Water Magician: Arc 1 Volume 2

Ryo’s life does a 180 after arriving in the city of Lune, where he spars with an expert sword-wielding elf, takes on guild jobs with Abel (his partner-in-adventuring), Abel’s party, and his roommates, and much more! Ryo never could have imagined discovering a whole different side of this new world! But then monsters spill out of the dungeon in droves and plunge the city into an unprecedented crisis. When Abel and his party set out to investigate, they’re forcibly transferred to the lowest level of the dungeon. There, they encounter a life-and-death situation against devils—creatures who eventually awaken as demon lords. The Handalieu Federation’s meddling and a confrontation with the Inferno Magician ratchet tensions up even more... With the dangers racking up one by one, Ryo finally gets serious?! “I won’t let you lay a single finger on this city or my friends.” Here comes the explosive second volume recounting the adventures of the strongest, freewheeling water magician!
