Review Detail of Nontr in Daily lazy life of sloth at high school DXD

I am dissapointed beacuse this is just a copy paste of 'mi viaje a traves del mundo'(ff in spanish) and some changes . Author just translated to english. Sorry if i give 2 stars but 'mi viaje a traves del mundo' was of my favorite ffs and at least i expected you could give credits to the author bc you other novel(a great harem king) is also a copy and paste of mi viaje a través del mundo. Hope i am wrong about this.
