After (almost) dying, Ritsuka Fujimaru was given a second chance at life in a new world. Well, since it's the world of a peaceful otome game, it probably won't be all that eventful. At least a certain holy maiden will be there at his side through it all.

In a timeline where Shirou Emiya would have become a Counter Guardian, a past love makes a final plea that changes everything. Being released from his future duties and sent to another world, all he was told was to "Be happy". But can he find happiness among monsters? Rimuru and co have something to say about that! Pairings undecided atm.
