Chapter 790: I developed Ecstasy

Seiji only allowed his mind to wander for a short instant.

This person was calling himself "Yakushi". Was that a code name or his actual name? Seiji felt that it was more likely to be a code name.

Yakushi, a high-ranked member of the Messengers… Seiji suddenly thought of the mystical drug Ecstasy¹.

Could Yakushi be the person that Yui previously mentioned, the only person capable of finishing the Ecstasy vaccine that could help ordinary people become immune to Spirit Worlds' influences!?

Seiji was quite shaken at this realization.

If that was really the case, then this doctor coat man was the main culprit behind so many people transforming into monsters!

Seiji felt anger rapidly rising inside him when he thought about how many monsters he had been forced to "clean up" by the Messengers so far.
