That time I was transported into another world with really hot guys but everything is gacha

Twenty-two-year-old Aether is a typical university student, who is perfectly content with his monotonous lifestyle in New Zealand, other than failing to nail down a girlfriend even once throughout his life. In the midst of a casual encounter with his colleague, he falls victim to a random assailant on the streets and is stabbed. However, while succumbing to his injuries, a peculiar voice echoes in his mind, and recites a bunch of commands which the dying man cannot make sense of.

When Aether regains consciousness, he discovers that he has reincarnated as a lady in an unfamiliar realm. In doing so, she acquires newfound skills—notably, the power to spend money for people and weapons to drop from the sky. She then stumbles upon the drunken bard "Barbatos" Venti who had been wandering for the past 300 years and wishes to save his dragon friend Dvalin. Sympathetic to his predicament, Aether, now Lumine, befriends him, promising to assist in beating up Dvalin.

Now, liberated from the mundanities of her past life, Lumine embarks on a fresh journey with a distinct goal in mind. As she grows accustomed to her new physique, her swiping antics ripple throughout the world, gradually altering its fate.
