I was looking at the glossary term for engage and it says "when the battle begins". So I was wondering: since Kensai's Blade has a Reaction it ignores the rule of location. If I have 1 Personality at provinces A, B, C, D and if as the Attacker I decided to fight battle A first, upon the engaging at battle A I can attach a Kensai's Blade to any Personality at province B, C, or D. Right?
[Mod edit : corrected syntax; please avoid abbreviations such as "prov" for province or "person" for Personality - LH]

Yes, per Combat Segment: "During the Combat Segment, [...] Reactions are not subject to rules of Presence and Location."
If I have 1 Personality at provinces A, B, C, D and if as the Attacker I decided to fight battle A first, upon the engaging at battle A I can attach a Kensai's Blade [thanks to its own Reaction] to any Personality at province B, C, or D. Right?
Right. Assuming you can pay all costs, Kensai's Blade's action lets you attach this card to any Personality whom you control at any location in play.
