Aililu Finnian

Aililu Finnian (also spelled Airiru or Alilou in some translations) is one of the identical twin sisters from the mercenary group Venus in the Maken-ki! anime (appearing primarily in season 1 and referenced in season 2/Maken-ki! Two).

She is the light-haired twin (blonde/yellow hair, blue eyes), contrasting her sister Lilu/Lilou (dark hair, green eyes). Both appear as childlike, doll-like girls who often speak and act in perfect unison due to their extremely close bond.

As SS-rank ability users among the most powerful in the series, the twins specialize in creating advanced space/time barriers (their combined ability called "Time/Space Keep" or similar). These barriers can isolate fights, contain damage, suspend time/space effects within them, and even restore everything to normal (including healing wounds) once dispelled. They mainly provide support rather than direct combat.

The Tenbi Academy students find them adorably cute (often calling them "dolls"), and they show a notable weakness to cats. Aililu tends to have a more monotone, emotionless demeanor, rarely showing strong expressions.

She and her sister serve as special investigators for Venus and interact with the main cast during their mission at Tenbi Academy.
