Sou

Sou (ソウ) is a monster companion in NewWorld Online and a supporting character in the BOFURI series. As he is Kanade's companion, he is affiliated with the Maple Tree guild.

Description
Sou is a Mimic (擬態) that looks like a transparent blob or slime, but it's called a mirror slime in the anime. Because of [Mimic], it can transform into other things.

Companions Arc
Upon reaching the 7th layer, Kanade committed the happenings to his memory. Once he felt enough information was out, he became attracted to a strange occurrence that could be found in rumors. While investigating it, he noticed an NPC he didn't recognize that wore equipment that would allow the NPC to be overlooked. After a game of cat and mouse and memorization, Kanade acquired a Copying Mirror and a delivery quest. Delivering the mirror allowed Kanade to test his might against the Mimic. Though Kanade won, he was jealous that the Mimic could freely use the spells stored in his Spell Stash. After taming the Mimic, Kanade named him Sou. However, in the anime, he followed the slime back to the house where it hid as a book, then towards a cave, this time as one of the rocks that is reflecting Kanade's appearance.

The player needs to be able to activate 50 unique types of skills and magic to revive and tame the Mimic after defeating it.

Eighth Event Arc
Dread and Drag spotted Kanade, and despite his skilled attempt at escape, they were dead-set on eliminating him. After they defeated him and moved on, Kanade emerged and picked up Sou. Sou had split his body, and the split died in the same way a player does. Because of Sou's effort, Kanade was able to gather valuable intelligence on Dread and Drag's companions.
