Takezō Kensei (剣聖 武蔵, Kensei Takezō) is an ancient human fullbringer who, after years travelling the world, has recently arrived in Karakura Town. He has the unique ability to absorb the life force of another being and use the absorbed vitality to fuel regenerative processes within his own body. Centuries ago, while still a youth and without much control over his own powers, he inadvertently used his powers to kill an entire army and absorbed the life force of tens of thousands of beings, the combined vitality stored within him effectively making him immortal.
