Kaifuku Lotion de Maou wo Taosu Koto ni Natta: Isekai Byuru Byuru Kouryakuki

High school student Aira Hagiwara never expected her ordinary life to end so abruptly, but one day she suddenly finds herself reincarnated in another world. To her absolute delight, she has been reborn as the Great Saint, a legendary figure destined for greatness. The realm she now inhabits feels incredibly familiar, mirroring the exact setting of her favorite video game. Thrilled by the prospect of living out a real-life fantasy adventure, Aira eagerly prepares to embrace her new role and take on the challenges that await her in this magical land. However, her grand expectations are quickly tempered when she discovers the extent of her divine gifts. The goddess who oversaw her reincarnation bestowed upon her only a single, highly unconventional ability: "recovery lotion." Rather than wielding devastating offensive magic or commanding holy swords, Aira is left with nothing more than a mysterious, slippery substance to aid her quest. Despite the absurdity of her situation, the fate of the entire world rests squarely on her shoulders, and she must somehow find a way to defeat the Demon Lord using only this peculiar power. What follows is a hilarious, slimy adventure comedy as Aira attempts to save the realm armed with nothing but lotion.
