The Villainess's Family Heirloom

A fresh graduate drowned herself and transmigrated into one of the fantasy games she had played. Of course, she would have been well-equipped to handle the world with no issue, if it wasn’t for her sealed memories. Armed with her family heirloom, Splintering, that lets her send fragmented memories to the past just before dying, she aims to navigate the world revolving against her.

But ruptured mana conduits, an underdeveloped brain, and a willful brother don’t seem to make the journey any easier. And when artifacts dictate the prowess of mages in the world, she is left with little choice but to recover her memories as soon as possible.
