Marietta-hime no Konrei. I want stories like that, which are soo sooo sweet and fluffy that you get diabeetus and barf sugar from reading. Simple as that.
Seven Unfortunate Lifetimes and Book of Bantorra (or the first arc, anyway) switch between diabetes and tears of anguish. Manuscript Screening Boy and Manuscript Screening Girl is wonderfully pure fluff. Manga has a lot more choices, like Tokyo Innocent, Mikakunin de Shinkoukei, Acchi Kocchi, Yumekuri, Akuma Jiten, Kitsune no Yomeiri, Hakoiri Drops, Kyou no Cerberus, and many more.
Demon Girl ~Tale of a Lax Demon~ If it's for my daughter, i'd even beat a demon lord Martial Arts Master
You're just here for the nuffies right? $10 to be paid for hush money first one: Started reading it a little while ago. 2nd: put it on my 'to consider' list. No anguish thanks, so first two ruled out. The Manuscript one, i read the first volume back when it had been translated. If more's been translated, i'll get back to reading it. It's been a while so i need to read it from the start again. I do remember there was lots of fluff. I couldnt make head or tales on the first one. Duke's Daughter: I read the first 4 chapters when they were first translated before the TL disappeared. will have to read from the start again and hope somebody with good pace and TL ability can pick it up to finish as its complete. 1st one: i looooooooove it. so much diabeetus and dark fluffyness. 2nd: I swear i started reading it ages ago but dont remember much. maybe will go back and read again.
