Scrolling through the manga artist's Pixiv account and all I can see are beautiful shotas and some are straight up femboy and crossdressing. So I'd say our little brother character is pretty much right up within our artist's alley.
He's probably talking about the other elf girl Char Antettman, an airhead elf who was a former assassin turned pastry shop owner. She's basically Jirei's de-facto sugar mommy and occasionally stays at her place mooching off her money while on the run from the rest of the harem members...
Getting expelled and later becoming a harbinger of catastrophe is nothing new.
We already have a certain guy who got expelled from a certain art school and years later becoming the epicenter of the world's greatest war in history.
Damn, that atmosphere almost went rapey there for a second.
Thank goodness Kei just happened to be at the right time and the right place to repel the would-be rapist.
Would be interesting if Almelia uses this as a pretext to break off the engagement with Lord Leonardia because his sheer incompetence (PTSD with cockatrice) injured her beloved maid (Serina) and worse almost killed her (Armelia) in the process.
My god the fucking author can't help themselves from keeping this trash around. How many arcs would they have to keep reusing this guy as a villain? Trash should stay 6 feet below the landfill I'd say.
