Espa - lowkey hates bugs keep roaches and flies away from her they are in danger. Not so pissy about butterflies and sometimes spiders but it also despises house moths with a burning passion. They have very little regard for life in general and bugs remind them of past missions in dingy, dirty settlements where nothing was ever clean and they just had to put up with it and also of their pre-weapon days where their quarters were barely spared any hygiene. Insects and dingy rooms and mould and the like awake those memories in them and they were not pleasant times. She doesn't realize this and just kills every bug in sight at a blink and if you asked her she'd just say "they're annoying."
Ciça - more normal. She isn't particularly a bug lover but she'll avoid killing them off whenever possible and will carefully put roaches outside when they get in. She is not particularly fond of mosquitos but she prefers repellents to rackets when dealing with them
Sabre - couldn't care less. He also dislikes mosquitoes and has no qualms about stomping on bugs but isn't particularly bothered by them either. If he sees a cockroack he won't kill it or take it out as far as he's concerned it's none of his business.
Juste - used to put fire at ant nests for fun as a kid
Ann - actually pretty chill about them. Won't go out of her way to keep them alive but recognizes you can't just expect them to vanish off the face of the earth. She will get rid of them when most convenient and can ignore them when necessary but won't make much of a fuss either way
HONORABLE MENTION: Radaça (one of ciça's grand-nieces) - really likes insects and bugs and finds them very cool and pretty. Probably has beetle charms on her phone case and bug doodles on the pages of her diary. She was obsessed with them at around 8 or 9 and it still sticks with her
Honorable honorable mention since you like them :) Key - is a little obsessed with cleanliness and perfection so they get a little uneasy at having roaches and spiders and stuff on the corners of the manor. It feels as if theyre failing at something. Will get rid of them and soak the spot with repellent and a harsh scrub as soon as they come across any. Outside of that scenario can actually appreciate them in nature. They find bugs a little cute.
If they find one indoors at another person's house they Will judge you. And think you are imcopetent. They won't vocalize that tho
