True-Consecutive Blade (真・連刃, Shin Renjin) is the powered-up version of Consecutive Blade, used by Souldragon cards and a "Finisher Move" type of Keyword, belonging to The SengokuDragonEmperor Burning-Souldragon alone, which released on BS34. Removing all of Consecutive Blade's weaknesses, it becomes a target attack-based effect which deals life damage based on destroyed/depleted battling Spirits.
In the design stage of the anime and cards, True-Consecutive Blade was originally the ability designed for Soul Dragon. However, to balance out the card power at the beginning of the anime and to make room for growth, it was adjusted to Consecutive Blade.
