Angel Knee to Front Kick is an attack used by Lili since Tekken 6. Sebastian can also perform the move in Tekken Tag Tournament 2. Interestingly, the attack uses Lili's original Front Kick attack from Tekken 5 Dark Resurrection as the ender. Unlike the original standalone move however, the attack does not knock down on normal hit, instead only doing so if the last kick is done on counter hit.
In Tekken 7 5.00, the second hit will trigger a Wall Crush on hit. Generally, the attack is useful as a safe string to use, as well as being a mix up since the other option Matterhorn Ascension is an unsafe mid attack that launches. The attack is also useful as a way to apply wall pressure as it will cause a wall stagger like stun that gives Lili enough advantage for additional mix ups when near a wall.
