Scorpion

"A lightweight blade speed-oriented Attackers often use: The Scorpion."

- Shiori Usami about the Scorpion

The Scorpion (スコーピオン) is a Normal Trigger that was created by Yūichi Jin to be Kogetsu's rival.

Appearance
The Scorpion is a trigger capable of shapeshifting, which means it doesn't have a default form, but it usually takes the form of a small sword of sorts. It can be shapeshifted at will.

Abilities
The Scorpion is capable of shapeshifting, and its ability to change is determined by the user's own skills and trion level. Someone with high trion level (i.e. Chika) would be able to use it like a fullbody armor.
