What I can think of is this:

Golem was presumed to be destroyed as Gravion, the core suddenly went into Oulu's programming and pretty much later Oulu developed Golem's mind and will and later manifests it's power. Lira recognizes Oulu as "Golem" and now has a new purpose to protect Lira at all costs.

This explains why Oulu gets a 7* form called as Zeldeus/Zell Deus and it's Extra Skill needs the Golem Core sphere to be equipped to Zeldeus/Zell Deus in order to activate it.
