When she thought she reincarnated into an eroge, her little brother who was the game's protagonist was also a reincarnator. Plus he was her past life's little brother too!? The protagonist's sister was not a capturable target, but with plenty of ero events: 'Alice'. As she evades her ero events she seeks the 'True Ending' with her slightly disappointing little brother 'Dean'. But she can't avoid the ero events.
