SAM's Kenki guage feels like a early stage of a Demon Blade/Muramasa Blade Guage mechanic by having it start was basic energy but maybe in a future expansion SAM may have to max that energy to activate the Demon Blade/Muramasa Blade Guage which may change the animations of SAM's combos attacks with increase potency and the main function is to maintain the Demon Blade/Muramasa Blade Guage and prevent it from hitting 0 by using the SAM's combos and Sen Skills.
