I hope you won't get confuse, but yes, the grimoire choose Asta.
I remembered reading that when the demon possesed Liebe, it killed Asta's mom. So, to avoid the devil from getting Liebe, she put him inside the grimoire since that is her power.
I remembered reading that Liebe said that the grimoire chose Asta.

It is Licht's grimoire! He was the elf boy who had the four leaf clover grimoire but it turned into a five leaf one when all of them were killed. Because when a four leaf clover grimoire owner is filled with hatred and sadness, Devil takes over him. So he turned into the demon then and Lumiere, the first wizard king and his human friend killed him............I hope you can remember now
I wanna ask sum of yall, who owns asta's grimoire? Her mother locked liebe in a book and then asta obtained the book? Wth? And then the arc with elves where it said that licht owned the grimoire omg my small brain hurts
