Kayac will release the largest update in the history of the Nintendo Switch game Ketsu Battler on July 30. The update, called Series 2, introduces the first paid DLC character, Kiden, a lightning-wielding fighter who is also the first in the game to have a counter skill. Kiden uses the Ketsu Ougi Counter to absorb an opponent's attack and responds with a massive lightning strike called Ketsu Divider. He costs 300 yen including tax. The update also adds a new system called Serious Zone, which activates when a player keeps attacking, wrapping the fighter in an aura and boosting basic stats while upgrading all Ketsu Ougi into Serious Ougi. The zone is more likely to trigger during long matches or when a player is behind after losing rounds. Four new stages join the lineup: Wide, Zero Gravity, Always Serious Zone, and No Serious Zone, bringing the total selectable stages to five with the existing Standard. All characters receive balance adjustments, and players can now set the number of rounds needed to win from 1 to 5. A half-price sale runs from July 30 to August 25, dropping the game to 250 yen.
- Kiden is a mysterious young man who carries an ultra-large sword on his back, and his counter skill gains a special effect during Serious Zone activation that forcibly draws the opponent in and guarantees the counter succeeds.
- The Serious Zone triggers by shaking the butt and continuing to attack, wrapping the fighter's butt in an aura; it is more likely to activate when a match is prolonged or after losing rounds.
- Four new stages join the lineup: Wide, which is wider than usual; Zero Gravity, a stage without gravity; Always Serious Zone, where the zone is permanently active; and No Serious Zone, for traditional battles without the system.
- The update adds the series' first stage select function, letting players choose from five stages including the standard Standard stage.
- Beyond balance adjustments, the update includes visual upgrades to character details and bug fixes.
- The manga's New Century Arc is set in the modern era after peace returned following the final battle with Ogetsu, and follows Kiden as the new protagonist.
- The half-price sale runs from July 30 to August 25 at 23:59, timed for the summer vacation period.
