I remember watching the anime years ago and recently made a friend watch it. Of course I watched it with them just so I could hear their reactions. I would love to read the manga so I totally support this suggestion!
I would also very like "Usotsuki" to be published, foremost because the character's dialogues are intersting and the protagonist's lies, to the reader and other characters, are, at least for me, both entertaining and unique.
Great novels to read. 2023 and we don't have this novels licensed, only VIZ first 2 light novels. Shakugan no Shana has a great fanbase, who knows if this novel can sell well or not... Maybe yes, nice anime, nice manga and nice novel.
In 2023 the volume 27 is out in Japan also. Praying for the license.
