Mizuhara Reito is an ordinary boy who wakes up in a world of 5 billion women and 5 men. Now it's up to him to repopulate the human species. Can he stay loyal to his missing childhood friend when all humankind is counting on him to sleep with as many girls as possible?
Mizuhara-san, I'm sorry, but the 
rules say you have to take that off.
Herr Mizuhara.
Lo siento, señor Mizuhara,
pero tiene que quitarse eso.
Lo siento, señor Mizuhara,
pero tiene que quitarse eso.
M. Mizuhara, merci de bien vouloir
retirer votre pendentif.
Signor Mizuhara, mi spiace,
ma da regolamento quello deve toglierselo.
Mizuhara-san, sinto muito, mas as regras
dizem que também deve tirar isso.
Простите, Мидзухара,
но по правилам вы должны это снять.
