I didn't like this fight. It had no feel to it.
If Ryu was to channel moves and spells from her old guildmates then we should see them, not have her summon avatars and just pummel the Juggernaut with her own spell.
Design-wise I just noticed that the Juggernaut was given horizontally slit pupils, which is generally a trait of prey/herbivors to increase peripheral vision in order to avoid predators.
