"To Darkness" will activate first. If you check the comprehensive rulebook, under the "Detailed Steps for an Attack" section, the battle will happen like this:

Step 9: Determine if the attack hits. If an attacking monster(s) has power greater than or equal to a defending monster's defense, destroy that monster. Penetrate abilities activate. If the attack was a direct attack to the opponent, deal damage to the opponent equal to the attacking monster's critical.

Step 10: A play timing to use cards or abilities with "Counter" begins. Abilities that activate when "deals damage" and "destroys" will be resolved here as well. ("To Darkness" resolves during this step.)

Step 11: "Counterattack" and "Double Attack" abilities activate.
