Younger sister of a major target in a dating sim world realises one day that She s reincarnated into a game she played in her past life. She befriends the OG FL (we love girls getting along for a change), all the MLs fall for her instead, and she learns to control her brother's strong, often out of control "transcendental" powers. It's good so far, I want to see the siblings become closer!
