One of the best (ecchi)light novel I have read If you are looking for : - a very very solid and well written story -perfect balance(in my humble opinion) between character building , fanservice and story -memorable characters and much more . -The concept is very refreshing and extremely well built. Then this light novel is perfect for you . Also if you are fan of the manga called ''Monster Musume: Everyday Life With Monster Girls'' then you are gonna absolutely love this light novel . I forgot to mention that if you can't decide if you should start the anime and after that to start reading thenovel , I suggest you to NOT do that because the anime (which covers until the the 3rd volume of the novel ) skips A LOT of important things from the novel , so I suggest you to read first the first 3 volumes at least and then start watching the anime . Also I know I am in no position to tell people how to spend their money but I seriously recommend you start buying the physical or digital edition of this light novel series , it would be great if we can support the author as much as we can .
