Big Spender in a Busted Game (2023)

Blurb:
Though the fantasy game “Mystic World” is maddeningly difficult and money-grubbing, Luda just can’t quit playing. So it’s borderline traumatic when the final boss, Lucid Black, destroys her precious kingdom in the final stage. But luckily, our heroine wakes up in the beginning stage of Mystic World as her game character, Princess Luda Earl Grey. Armed with tons of S-rank items and her credit card, Luda might just have a shot at saving Milk Tea Kingdom from the deadly Lucid. And the first step in her plan … is to enroll in the same academy and befriend her worst enemy!
