Hello Bookworm! I looked it up, and the Library in Alexandria — which just so happens to be the greatest in all of Yurgenschmidt, nay... even the entire world — has the following entries:

Secrets of the Silent Witch by Yen Press: 📖 Vol. 1, 2, 3, 4, 4.5, 5, 6, 7; 🖥️ Vol. 1, 2, 3, 4, 4.5, 5, 6, 7; 🎧 Vol. 1

I couldn't find a series with the name "Secrets of the Silent Witch -another-, Vol. 1: Rise of the Barrier Mage I". Maybe you should write it and send a copy to my library. In fact, I think this is a great idea and you absolutely should do so. Right now. Chop chop.

I couldn't find a series with the name "The Water Magician: Arc 1 Volume 4". Maybe you should write it and send a copy to my library. In fact, I think this is a great idea and you absolutely should do so. Right now. Chop chop.

Magic Stone Gourmet: Eating Magical Power Made Me The Strongest by J-Novel Club: 🖥️ Vol. 1, 2, 3, 4, 5, 6, 7, 8, 9
