I just cannot see what could happen that could lead to Harald betraying Imu.
- He chose the WG over his best friend
- Knowing full well how bad they are, Harald willingly became a celestial dragon
Even creating an army for Imu shouldn’t be a disqualifier because Harald said several chapters ago that he wanted more giants like John Giant in the WG.
Harald having a change of heart would be an asspull. People like this irl don’t change.
Loki and Jarul should just recognize Harald as a threat to Elbaf and decide to kill him.
