The Eccentric Master and the Fake Lover, Volume 1 ROKA SAYUKI ITARU
Nichika's fate has been foretold by a man claiming to be a witch, and it spells doom. What a thing to be told right after tumbling into another dimension!
Bodily fluids--in other words, tears, spit, blood, and even--yup, kissing.
With the threat of death snapping at her heels every day, Nichika finds a way to beat the arrogant, selfish, and eccentric Witch Oswald at a bet and gets him to take her as his apprentice as a last ditch measure to stay alive. Now bound to him by magical contract, Nichika joins Oswald and his talking wolf on the run from the Witch's Council as she tries to find her way back to Earth. Though they're a mismatched master-apprentice duo, they have no choice but to travel across magical lands filled with fantastical creatures to escape the constant danger closing in on them.
