Tensei Ouji wa Daraketai

I, Haruto Ichinose, am a college student that reincarnated as the Phil Grishart, the youngest prince of the small country of Greshart. My previous life was full of restraint, so in this world while petting my beloved fluffy pet, I'm going to live a life full of freedom! Or so I thought... But starting from summoned beasts to spirits, ores, and monsters. The more I know about this world, the more evident the outbreak of trouble is. I want to live a lazybone's life, but it's not possible at all!
