That Hakkai is more accustomed to random spells and explosions is honestly concerning, but Hakkai does have an (apparent) calmness to him. He also seems a little more forgiving if there's a scorch mark than Nari, though Ginia only knows Hakkai marginally more than Joss's other god.

(Also she's never been on the end of Hakkai's passive aggressiveness.)

"For the record, we're not working with a flame larger than a candle, okay?"
