Danna as a serious fan of Isekai novels and webtoons, one of her dream wishes was to be 'isekai-d'- that is to experience transmigration. But when it really came true...it was not truck-kuns doing? But by a Scam- like Isekai Aplication form?! After filling the form, Danna became a member of an organization called The House of Afterlife, After they processed her papers, she was now ready for transfer. But soon,Danna realized that she was not the protagonist, nor is she the villain, she was also not a side character or even a cannon fodder but only a mere background character?! No worries! This Background Character is the type that apears on every novel or webtoons anyway, since this is the case...hehe. Let's just go collect male leads like a pokemon!
