"How easy..."

The prompt was "Draw or write about your character fighting the boss!". So I drew Kiritana cutting the slime in half, using the wind to move and enhance their abilities (which is something they already did, but it also fits their Latent Element). Even if the slime is able to put itself back together, Kiritana's slashes are debilitating, and it'll probably take a while for it to regain its full form and its strength.
