Taking its inspiration from the Shunsui Kyoraku character from Bleach, Theatre is a Shikai/Bankai Element for Shinigami in Type Soul. It’s a rather powerful one, so let’s take a closer look at it.
Theatre is a Legendary Shikai Element. This means that it has a drop rate of 3%. Once you receive your Shikai, if it’s not the one you want (which I assume is Theatre in this case) you’ll need to use a reroll to try your luck again.
Getting Shikai is an early task for Shinigami. For full instructions, you can check here. Then in order to get Bankai, you’ll need to jump a great many more hurdles, which are outlined right over here.
Shikai
Z – Kageoni – This causes you to teleport behind your opponent with an opening attack. It will ragdoll the opponent and can be followed up with a combo.
X – Wraith – A quicker but less flashy teleport that will move you in front of your opponent with an attack.
C – Iro Oni – This puts you in a stance. If your opponent hits you while you’re in this stance, you’ll teleport (of course) and hit them from behind, causing them to ragdoll.
Bankai
T – Plague – This is an AOE (area of effect) move that will mark all the enemies in your vicinity. After a few moments, it will stun and damage the enemies.
G – Final Play – This has a long(ish) windup that then releases a massive slash in front of your character. It guard breaks anyone in range and does massive damage.
