Y

Y is an old friend of the protagonist from their shared academy years, now serving as a United Nations researcher dedicated to investigating human heritage sites. Outwardly composed and deeply knowledgeable, she harbors an intense passion for fujoshi culture beneath her professional exterior. Even in a world marked by civilization's decline, she channels her extraordinary drive into promoting doujinshi culture and organizing indie events—often leveraging her official position to indulge her personal obsessions. This striking contrast between her serious role and hidden enthusiasm makes her an indispensable supporting character.
