hey Dara.
took a look at your request shop.
Demande de Hakuryuu translates as request of Hakuryuu.
if you wanted to say requests with an s it's demandes
Les demandes would translates as 'The requests'
and also, when placing de behind a vowel or h (in french the h is silent) there must be a ' after the d.
so, Les Demandes d'Hakuryuu would be the correct title.
if you're going for singular, it's 'Une Demande d'Hakuryuu.'
Just pointing that out. *knows french. XD*
