My Instant Death Ability Is So Overpowered, No One in This Other World Stands a Chance Against Me!, Vol. 8 (novel)

Having reached the island nation of Ent, Yogiri and Tomochika continued their pursuit of the Sage Yoshifumi and his Philosopher's Stone, which led them into the Elven Forest. The forest proved to be more than meets the eye, however, as they discover that the space within it is warped and twisted, leaving them hopelessly lost with no clue as to how to escape. And while thanks to the machinations of a certain vulgar classmate they can hopefully say goodbye to the meddling of Malnarilna, it doesn't take long before all sorts of other troublemakers start turning their attention towards the hapless pair, making their impossible journey through the Elven Forest even harder. And, wait, where did we leave those other three Philosopher's Stones again…?
