ヘブンズゲート

A huge angel that is herself the Gate to Heaven. Originally a Cherubim, she was assimilated into the Gate, and ordered to guard it by Ilias herself. Rather than prevent surface dwellers from getting into Heaven, her true purpose was to restrict angels from freely being able to reach the surface world without Ilias’ permission. She was granted free control over devouring any who would attempt to unlawfully pass the gate, and render judgement as she saw fit. Since she’s easily bored during her eternal duties, she would violate any trespassers for an eternity. [From In-game Monsterpedia]
