Vase

Vase (ヴェイズ) is a member of the magic cabal Dusk Waiting to Awaken, who appears in Toaru Majutsu no Index SS: Necessarius Special Admission Test. A loyal member of the magic cabal, he continued the goal of the magic cabal even after the defeat of their leader Arlands Darkstreet, becoming de facto leader of the group.

Personality
Vase is the type of person who focuses on supporting people from the background and sees no meaning in taking command, regardless of crisis or opportunity. He believes in the idea that pride, both from overestimating and underestimating oneself, comes before a fall, also seeing it as identical to stagnation and leading to death. As such he seeks to survive by avoiding becoming prideful and stagnant, aiming higher while showing there is still more room for improvement.

Vase was contacted by Arlands Darkstreet as Arlands was transporting the Necronomicon and told to make as many preparations as he could. After the ceremony to summon R'lyeh was carried out, Vase received the transmission with the data that the cabal was after and led his group to Stonehenge in order to construct the spell Blank Paper.

Abilities
Like other members of his magic cabal, Vase uses magic based on the Cthulhu Mythos.

The Haunter of the Dark
Using the "Shining Trapezohedron" (輝くトラペゾヘドロン) as told in "The Haunter of the Dark" Cthulhu Mythos story as a basis, he has a trapezohedron-shaped jewel with him to represent the jewel found in the story. In the story the Shining Trapezohedron was the medium used to summon Outer God known as Nyarlathotep (ナイアーラトテップ) and was normally kept within a special box while supported by seven pins. The jewel's power was not invoked when the seal was broken. Instead, it summoned Nyarlathotep when the lid was closed and the jewel was covered in darkness.

When preparing to make use of the spell, Vase tears a piece of paper several times and twists it to look like it has seven sharp stakes sticking out of it, resembling spider legs or fangs. He then sticks it to his car's door. Vase makes it so that his car represents the box where the Shining Trapezohedron was kept by using the piece of paper. Even if the “box” itself is fragile, it still has the seal needed to switch between summoning the evil god or not. Once that seal is made, the inside and outside are fundamentally cut off from each other.

Using a jewel simply known in the narrative as a Trapezohedron (トラペゾヘドロン), he needs only to invoke a chant and then cover the jewel in darkness to summon Nyarlathotep as he appears in the mythos story. The spell summons a mass of black smoke and lightning shoots out in every direction. This lightning is enough to knock a fully grown man like Tatemiya Saiji unconscious.

However, as the jewel requires darkness, no matter how forceful the method, any light reaching the jewel is enough to end the ceremony. When exposed to light, the black smoke disappears instantly.

The chant:


 * "From the moment I become involved with you, I vow that I will not return alive. Oh mocking god, use the darkness filling this stone to destroy everything for this one last night."

The Thing on the Roof
Vase also uses a red jewel, which he swings around in a leather belt like a sling and then propels towards the target like a missile. When the red jewel hits the target, it emits a pitch black darkness, which then absorbs the target completely even their screams. The jewel represents the red jewel that is said to call in a frog-like evil god found in some story in the Cthulhu Mythos. Most likely, this refers to the toad-like red jewel found and the unnamed creature that is looking for it found in the short story "The Thing on the Roof" by Robert E. Howard of Conan the Barbarian fame, and one of Lovecraft's correspondents in weird fiction.
