If i am not mistaken The OVAs in season 1 was not from LN materials, yes Ishibumi wrote the OVAs script but the problem is it's still not as original as the SS version (fillers) in the LN. Ishibumi could just focus on the LN version without worrying to write the script any OVAs anymore because the SS version could serve the purpose of OVA
