[Sclerotium: Era of Symbiosis]

Sumu - the cleaner of Xudu. In three years and one thousand and ninety-five days, he personally pushed countless people into the correction factory. He thought he was numb until he heard a sound in the wall. A golden mark, a talking ancient sclerotium, turned him into a half-human, half-bacteria monster. He is also the only one who can hear the wall cry.
