Muteki no Ansatsu Madoushi, Last Boss Musume to Tabi wo Suru @COMIC
無敵の暗殺魔導士、ラスボス娘と旅をする@COMIC
Once hailed as the strongest mage alive, Brad Lester withdrew from public life after his young daughter died and took work as a common labourer. When the World Peace Promotion Association kills his wife in pursuit of his abilities, he sets out for revenge, only to discover that the organisation's leader, Valburga, has been turned into a small girl with no memories and nowhere to go. Unable to look at her without thinking of his daughter, Brad takes his sworn enemy along on a long road through the Olford Ancient Magic Research Institute, the mouse-worshipping town of Brooke, and the snowbound village of Lutz.
