I eagerly await the moment when Bell reunites with his grandfather Zeus and uncovers his true origins, along with everything related to his birth families, including their struggle to complete the three great quests and their defeat against the OEBD, aiming to make the dragon's defeat Bell's personal maquia.
I would also like Bell to receive something from them for being their sole survivor, similar to how Ryuu received Astrea Record due to her affiliation with the extinct familia. This would serve to empower Bell as the main combatant against the dragon, since, by level, it doesn't seem like he will become the strongest. Moreover, there must be some narrative reason for Bell to be their last survivor, and a skill derived from their ancestors would fit well for that purpose.
