Shin-Zantetsuken (真・斬鉄剣, Shin Zantetsuken?), also known as Shin-Zantetsu and True Edge, is a recurring ability in the series. It is generally an upgrade to the signature attack Zantetsuken, and generally has a much higher chance to inflict Instant Death to all enemies than Zantetsuken.
Shin-Zantetsu is an ability of the Samurai Dressphere. It is the upgrade to Zantetsu, and attempts to inflict Instant Death to all enemies instead of one enemy for the cost of 32 MP. It requires 100 AP to learn and requires learning Momentum for it to appear at all. Learning the ability will unlock Zantetsu.
The Raiden card references Shin-Zantetsuken by Breaking two Forwards when played, acting as an upgrade to the effects of Odin's cards, which Break one Forward.
