Sislau

"I know you Adventurers are hiding some delicious desserts. No matter how hard you try to live in peace, my mates never overlook."

- Sislau, TRPG Replay 2 chapter 4

 is one of the Geniuses of the Fourth Hour and the Genius of Pestilence. He made his first appearance as the main antagonist of the TRPG Replay 2.

He is also known as Sislau of the Pestilence (疫病のシスラウ).

Appearance
Sislau appears as young fairy boy that is about 30 cm in height and has butterfly-like wings. In the TRPG Replay, they are purple, though in the anime they are largely beige with purple accents.

Personality
Although he has a contemptuous attitude, he himself has not meant to be deliberately offensive.

Synopsis
His wing scales are virulent poison that can taint lands, brainwash monsters, and give a semi-perpetual abnormal status "Pestilence". He polluted Cornu River that flows near of Akiba to brainwash Hill Giants that had ruled the Plains of Bodarel into becoming his army. He was eventually killed by the members of Nyanko-tei.

He is mentioned in Chapter 2 of volume 10, Homesteading the Noosphere and makes an appearance in Season 2, Episode 22 of the anime.

Trivia

 * Like all other Genii, Sislau derives his name and epithet from the Nuctemeron.
