My Instant Death Ability Is So Overpowered, No One in This Other World Stands a Chance Against Me! ¿ - AO¿, Vol. 5 (manga)

Yogiri and Tomochika continue on their way through the Tower of the Trial in hopes of escaping before it comes to light that Yogiri has not only killed the Dark God, but has also started to do significant damage to the tower itself. The other participants are not so understanding, however, and seem determined to stop the two high schoolers at every turn. At the same time, the Sage Aoi follows Yogiri and Tomochika’s tracks to the tower just in time to witness the arrival of an infamous Aggressor known as the Hedgehog. As ever more supernatural beings converge on the swordmaster’s trial, it becomes clear that getting to the capital will be even more of a chore than Yogiri and Tomochika had imagined.
