Grimgar Of Fantasy And Ash Vol. 5 (Light Novel)

Level 5: Hear Me Out, and Don’t Laugh
“…So, what do you think this is?”It has been several months since Haruhiro and his party came to the Wonder Hole. They have been slowly but steadily improving their skills as they make their way through the labyrinth. Then, while exploring, they happen upon a hole they’ve never seen before. A hole that, as far as they remember, wasn’t there the last time they passed by three days prior. It may lead to an undiscovered new area, which would benefit them greatly if they’re the first ones to explore it. Haruhiro is unsure whether or not to venture into it, but Team Tokimune, a group with a reputation for being eccentric but capable, appears and proposes exploring it together. New encounters await them as the adventure story born from the ashes continues.
