Your typical cringey anime fan.

Killians are rather antisocial, and quite unfortunate to have never experienced their first kiss. Killian's generally express their names with pride on items of clothing, such as school jumpers and hoodies. Killian can be a real name, or to cover up a shameful one.

Killians often enjoy odd combinations such as honey in their tea, while watching anime/manga.
It's highly important that Killians DO NOT watch mainstream animes since they must be different from everyone else. Killians tend to ditch social events like parties or social gatherings for watching Anime or game trailers.

John: "Dude you're such a Killian"
