Full Clearing Another World Under a Goddess with Zero Believers (Manga) Volume 8 by Isle Osaki

While the rest of his party is enjoying a relaxing beach vacation, Makoto tries to explore the last dungeon where Noah is trapped: the forbidding Seafloor Temple. His water affinity and elemental magic should make him well equipped for the task. However, if he wants to step foot into new territory, he’ll have to contend with giant monsters and an almighty goddess! Later on, Makoto and his friends finally make it to Highland, but like a bolt from the blue, he’s suddenly challenged to a duel by Gerald Ballantine, Highland’s very own Hero of Lightning. Gerald may be arrogant, but he’s got the strength to back it up! In a one-on-one sword fight, Makoto is at an overwhelming and potentially deadly disadvantage. Will Makoto’s water magic be powerful enough to turn the tide and defeat Highland’s hero?
