So What's Wrong with Getting Reborn as a Goblin?, Vol. 5 - Nazuna Miki - Bog

Most goblins are lucky to see their seventh day-but not Akira! Once an ordinary Japanese salaryman, he has dedicated his second life as an exceptionally long-lived goblin to making a utopia for goblinkind, where weeklong lives are not tragedies but rather the rhythm of society. Until one day, Akira ministers to a goblin on her deathbed, and she abruptly resuscitates...with an even stronger skill to boot! This evolution transcends the system built by Akira and presages a great change in the goblin village-and maybe the whole world...?!
