Reflector (攻性防禦, Hōsebōgyo), also known as "Assault Protection". The main Parry staple of the series, by pressing 
and 
button simultaneously while standing, crouching or in the air. When opponent attacks, the player will have not only avoid chip damage, and saving guard gauge:
- Able the cancel to other moves or another parry when opponent uses the attacks that aren’t close to the player, or while straight through above the player (as seen when against Valkyria).
- Auto counter when against opponent’s attack at close range called Interceptor (要撃攻性防禦, Yōgeki Hōsebōgyo). Can still cancel to other moves.
As of EN-Eins Perfektewelt, Reflector can also be done simply with 
button, same goes for EX and Super Moves.
EX Reflector, dubbed "Heavy Assault Protection" (重攻性防御, Jūhōsebōgyo), or Heavy Reflector currently only exist in UNDER NIGHT IN-BIRTH II: Sys:Celes.
