Sangatsu no lion Natsume yuujinchou Haikyuu Ookiku furikabutte Days Well these are just my preferences tho
Code Geass R1+R2 Psycho-Pass Boku dake ga Inai Machi (all good things come in threes but I'll keep going) Parasyte HunterXHunter(2011) Re:Zero No Game No Life (things that come in sevens are blessed with greatness) Have fun over your vacation!
