High school student Yuge Itsuki was sent off to a strange parallel world with his childhood friend Konatsuki Mahiru. It was the magical world of "Granvania", which was facing a crisis from the threats of "Impurities." Itsuki was summoned to this world as a "Visitor" to save this world, but to accomplish this mission, he had to perform a ritual known as the "Love Rituals..."
That said... being surrounded by twelve 
beauties, you'll have a literal harem!
عدا ذلك... كونك محاصرًا باثنتي
!عشر حسناوات، ستحظى بحريم حرفيًّا
Wenn du also von zwölf Schönheiten umgeben bist,
hast du buchstäblich deinen eigenen Harem.
Y estando rodeado de 12 bizcochos,
tendrás todo un harén.
Y estando rodeado de 12 bomboncitos,
tendrás todo un harén.
Et puis, avec ces douze beautés,

Detto questo... 12 sventole che
ti ronzano attorno è praticamente un harem.
Sem contar que, cercado por doze
Sacerdotisas, vai parecer um harém.
То есть... ты будешь окружён двенадцатью 
красотками! Настоящий гарем!
