Aquilo is a knight currently guarding Sagittarius

Many people seem to confuse Aquilo's admiration for Sagittarius. They think that Aquilo might have romantic feelings towards him. He denies it every time but people somehow end up thinking he's lying.
No one really knows what his sexual orientation is -

Aquilo isn't someone who easily opens up to others. Any new recruits that join Sagittarius's forces have a very thorough background check that is conducted by Aquilo. He doesn't want any harm to come to his comrades or to Sagittarius.
Currently the only people he fully trusts are Khione (his sister), Sagittarius, Libra, Virgo and Mettaton (even though he's a goon).

yo go look at his sister while you're at it : ]] - Khione She's such a beaut
