Solemn Lamenting in Another World

You know the usual isekai trope, right? You know, the ones where you walk on the road distracted by whatever the hell you're doing, gets killed by the nefarious Truck-kun, being send to afterlife by whatever deity owns it before asking what you want to be or have when you get reincarnated, and BAM! Another world. A bit cliché, right?

Yeah, uh, one problem... You ask for an E.G.O. Gift, more specifically, the Abnormality Funeral of the Dead Butterflies' Solemn Lament E.G.O. when you get isekai'd but you got turned into Yi Sang in the process.

You got what you want as someone playing all of ProjectMoon's games, I guess. Possibly scare the local populace and another guy who gets summoned by a kingdom to defeat the usual Demon King cliché with a JRPG system.
