I see! [That settles that for Ishimaru.] If you do not believe that we have met before, then we must not have! I believe that I confused you with another me... Allow me to explain!

[Time to explain more to his other self.]

During one event that transpired here, mysterious rips opened between different worlds. In that other world, I did meet someone another version of myself who dressed like you and belonged to an organization. It must have been different from the one you have come from! I apologize profusely for the confusion, Ishimaru-kun! [He says with an apologetic bow!]
