Demon Guns: Bolverk

The Demon Guns: Bolverk (魔銃・ベルヴェルク) is an Arch-Enemy Event Weapon in the shape of a pair of handguns. It is wielded by Noel Vermillion, and previously by Three and other people.

Information
The Demon Guns were created during the Great Dark War by Nine, and it uses a part of Takemikazuchi’s core. It had a multitude of owners, including Three of the Ten Sages. Bolverk was given to so many owners over time, and was lost after the war, with its core being never released.

The present wielder is Noel Vermillion. When she was still a child, she was attacked by a monster – then, for some reason, Bolverk suddenly appeared in her hands allowing to protect herself. Since that time, the Demon Guns are with her.

Bolverk can perform attacks at will in the desired location, regardless of walls and other obstacles, detonating a Magic Formula-based blast wherever one aims it. Its standard form is a pair of handguns. It is able to change its shape, and the following forms were seen:
 * Fenrir (フェンリル) — a multi-barrel machine,
 * Freyja (フレイヤ) — a shotgun,
 * Thor (トール) — a recoilless rifle,
 * Sleipnir (スレイプニール) — a machine gun.

This Event Weapon served also as a limiter to hold back Noel’s unstable emotions, not allowing her to awake as a Dimensional Boundary Contact Prime Field No. 12, Mu. Eventually, her strong hatred unleashed the limiters, and Yūki Terumi smelt Noel into the God Slaying Sword, Kusanagi.

Trivia

 * Bölverk is one of the names of Odin, which means Evil Worker or Evil Deed.
