A Unison Combo is a battle mechanic in .hack//Link. It is activated after the target enemy's guard has been broken and it is struck by the final hit of a combo or art. During the Unison Combo, Tokio and his partner alternate using arts on the enemy. Tokio's attacks are triggered by a bar on the bottom of the screen. The sweeper is stopped by pressing the O button. If the sweeper isn't stopped or is stopped over a black area, Tokio's attack misses and the Unison Combo ends. If it stops over a green area, his attack is ranked "Nice!" (one star); if it stops over an orange area it is ranked "Great!" (two stars); and if it stops over a yellow area it is ranked "Excellent!" (three stars).
If the Unison Combo ends by the enemy's HP reaching 0 or by reaching the maximum amount of returns, a Unison Combo Finish is activated. The Combo Finish has up to 4 levels, and the level of the Finish depends on the number of returns and their overall ranking. Tokio names these strikes himself, and some if not all of them are named after moves in the game Akashic Line.
