Helosium

Helosium is a heavenly summon that Laila and Nanael accidentally sent to the Continent, causing it to unintentionally  wreak havoc upon the land.

Appearance
Helosium takes on the form of a giant, humanoid figure composed of solidified Holy Milk.

Abilities
Helosium is able to stretch itself out to attack its enemies and can erode clothing and even rock with just a splash from its body. Because of this, melee attacks are rendered useless against it. Helosium's only apparent weakness is its core, which can be destroyed by a powerful direct attack.

Trivia

 * Helosium seems to have a penchant to only capture women, although this can be explained, as it's orders were to capture the Swamp Witch.
 * Helosium seems to be inspired in shape in Shinji Ikari's EVA-01 from Neon Genesis Evangelion, except being stripped from its armor. His weak point is also a reference from the same weak point used by the Angels from the same series, since they need their core to be destroyed just to be able to defeat them.
 * The way Laila destroys it resembles how the EVA-01 destroys Ramiel The Fifth Angel during Operation Yashima in Evangelion in the same way in the sixth episode from the same series.
