"The Ugly and the Beast," Anna Brussha Once upon a time, there was an ugly girl: a white sorceress with a pearl veil over her eye. She ran away from her imposed betrothed and ended up in the lair of a dark wizard. Once upon a time, there was a beast: a black mage in terrifying bone armor. And his heart was hidden in darkness and cold until a bright enchantress burst into it. And they lived... Whether long or happily is a mystery sealed behind seven seals. 

"Mistress of the Route 'Other Worlds,'" Sanna Syu Do not swear or ask, if you are not ready to repay the debt. I did not know how my request would turn out and promised to pay with delight for the life of my little niece. Who knew that "delight" is the currency of other worlds, and I would have to bid farewell to my familiar life to repay for the service? Now I am forced to serve as the mistress of the route 'Other Worlds' for many decades... or speed up the process by getting involved in an adventure. Maybe I will manage to outsmart the impartial mediator - an inter-world intermediary in conflict resolution? No? Or to make him fall in love with me and become my husband? I think I will try.
