The title seemed very Japanese (bad) to me in terms of "this one wants to be informative" So honestly I read it out of inertia due to the central work of the car "... Card Apprentice", so I think it will be difficult for you to attract public. But it is certainly an engaging story and the author generally knows how to handle good lore and power systems. Something that I think could attract an audience would be to change the word toy on the final cover and that screen does not match. Additionally, I have always wondered if the author plans to have a Discord since, for better and worse, this interaction at least helps readers to be attentive to updates and even more so when they do not have fixed updates like currently.

It's my intuition but I think the librarian or his son is trying to create a similar method to achieve "rule unity" using the ability to free oneself from pixies. Or failing that, Wyet will develop it.

he should have tried teleporting from the dungeon seal. This way he would check if in the future he can use it to free bloodyte

I have a question, the elemental blood swordsman hasn't died right? It is assumed that he stayed in a bloodite cave to meditate on the blood rule. Although bloodite ate his body but his gem could always rebuild him. In addition to this, if Wyat gets the rune-core from him, will he create an elemental and/or experiment with the core?

I understand why he has two sets of mind splitting skills, since he has two sandalwood. But how does he get the two sets of the cocoon ability for the two cards?

what is the next book?
