Maken

"If you wish to kill, simply grab my hilt. I promise, you will rise victorious"

- Maken, also known as Gram Maken (魔剣, Demonic Sword), more commonly known as Gram (グラム, Guramu lit. Wrath), is the name given to a sentient sword, rumored to have originally been a Demon, and is currently owned by Rhea Euryale.

Appearance
Maken, or Gram, is said to have the natural ability to change it's form to a different weapon that suits its current wielder, doing so in order to be effective for his owner, but is only limited to inanimate objects.

In Rhea's ownership, Gram takes the form of a medievel-like broadsword with a pitch black blade with edged spikes on the corners of its blade, being nearly the same length as Rhea's height, it's hilt is also pitch black, but it's most distinctive feature, is the deathly pale, four fingered hand grabbing the hilt, with a marking said to be Gram's "eye". The hand vanishes into thin air whenever Gram is used in combat, but forbids anyone else from using him aside from his current owner.

Personality
Gram is a malicious entity, claiming to solely exist for the thrill of battle, hence why it relies on others to wield him, since he can't do so on his own, but even so, still shows no care for even his wielders, seeing them as nothing but tools he can use in order to enter a battle.

While he is capable of communicating with humans, he only does so with his owner, yet even then, his only comments would be an attempt to persuade them to enter a battle, even if his owner has nothing to do with it, even going as far as commanding them to fight because he wishes to have a fight.

Trivia

 * In Norse Mythology, Gram is a sword used by Sigurd in order to slay a Dragon named Fafnir.
