hi aries,
yup i've heard of Omar Camar and his dojo in quiapo. but AFAIK he originally taught combat aikido like mr. gavilleno, right?
and no, we only refer to the one handling the class as sensei, otherwise i call them sempai.
anyway for those reading this post, combat aikido (i think) is a system developed by one of the senior aikidokas here, mr. gavilleno i think was part of the first few batches when aikido started in the philippines, i think it's mainly a combination of aikido and street fighting (or something like that)
unfortunately, i dont know why he branched out and developed his own school and i don't know if he's still affiliated with aikikai hombu.
regards,
adrian
