[Chiaki dutifully takes her part near the back of the conflict, summoning her moogle Mogomi to join the fray roughly between where she and Jack are standing.]

I'll support you with healing from the back row while Mogomi casts spells, okay? Let me know if you need me to change tactics mid-battle.

[With that, Mogomi takes up her role as lead spellcaster, flinging a Thundara spell at the golem as Chiaki casts a Cura on Jack. He's going to need a lot of healing to make it through this.]
