^^ I'll second that. I definitely liked Marcille's dynamic with Falin, but the last few volumes of the manga seemed to place more emphasis on Marcille's relationships with her friends as a collective(particularly her desire to not outlive them as an elf) rather than her relationship with Falin in specific. Still, I definitely recommend the series.
Helia non-stop banging Coralie like the naughty dog girl in heat she is to impregnate her, shooting loads to the brim every 25 minutes, Coralie wanting to have her beloved's children and have more people to play video games with.
There's no actual canon basis for this ship. Most of the art of this pairing is commissioned by a single person. Same situation as Eunectes/Ho'olheyak.
