Wand of Fortune R2: Jikuu ni Shizumu Mokushiroku

Lulu has found a partner capable of steadying her chronically misfiring magic — except the magic refuses to be steadied. A serious misfire scatters the entire group of young mages 350 years into the past, where they must navigate a completely unfamiliar world, respond to crises that were never their problem, and encounter people they were never supposed to meet.
