The more I see the LN story it makes me think.
1. Hestia familia needs more growth without Bell.
2. Bell needs better training.
I'm loving the choices of character development with the thought of Bell being forced to join Freya familia to save his goddess and friends but going with conditions to leave in a year.
This is only a thought but I'd love see Bell bequeath the knife to Lili and in a way force Hestia familia to run to catch him while he in a sense goes to college in the Freya familia.
The battles fought without Bell by hestia familia tend to be some of the best in the series. I'd love more of those.
Lastly with a new dinamic for Hestia familia it allows a spot for characters both adventurers and gods to come in.
