Doudemo Ii Sekai Nante: Qualidea Code

どうでもいい世界なんて－クオリディア・コード－

Set before the events of the Qualidea Code anime, this light novel is the Chiba leg of the franchise's three-author project. Kasumi Chigusa and his sister Asuha stand for the defence city of Chiba, and the volume turns on the scheming and strategy over who holds its top seat while the war with the invading Unknown grinds on around them. Like the rest of the project, it is set in a world where children put into cryogenic sleep during that war woke with individual powers called Worlds.
