My Companion is the Strongest Undead in Another World

Briefly about My companion is the strongest undead in another world Manga.

Yuma is a shy college student who has been summoned to another world. What awaits him there is not a sweet welcome, but a real hell, where fear and pain permeate his entire body. “Why am I here…?” – he screamed as his immortal body regenerated.
Yuma became a lab rat to researchers who were fascinated by his ability. But his otherworldly life changes dramatically when he meets a girl named Eve!

For those who are curious, through Twitter (apparently the author or artist) found a Japanese online store that has 4 volumes, so at least the author hasn’t abandoned this work. The idea is there, the development is also present. The characters hooked me. The vampire Eva has the vibe of Rouge. But “high connoisseurs” is advised, too much here. I read this as an everyday comedy with elements of harsh sadism, so I got it.
