Revamping Air Bullet and Flash Steps

"Can I borrow your Domain of Valor and the Bulwark of Invulnerability, Daisuke?"

Hikari asked when she stood up after being sent flying away by one of my clones. She dusted herself by casting a 4-node Elemental Spell, Refresh. It's a simple spell which involves showering her with Water Element before drying it instantly under Light Element.

Back when they were running away, she sparingly used this kind of spell to preserve Elemental Energy but now that she's back to the Human Territory, she once again became relaxed. Still, the deaths of the 14 elite of Humanities was still weighing on her shoulder. That's why she's already here, training with me without waiting for the others.

Elemental Absorbing Realm can at most create or cast a 3-nodes Elemental Spell which only involves one Element, their Main Element. The way I could use Spark could probably be attributed both to my Aether Elemental Core as well as the Flux Energy.
