E.I.K.O. - 63067 Offenbach Berlinerstrasse 238

I found these stickers at the reception window at the hotel in Podgorica. How come some German-Japanese group to be adding something like this? There was an Italian one also below. I'm guessing that these martial arts organizations would be robbing people by the planned injuries such as causing the elbow to be broken to cause the arm no longer usable. Also for the eye injuries for one-eye people making. The bullied people could return the martial arts clothes back to the organization and the team leaders would be selling the used clothes to the new-comers for money making. The ones lost in the training would make a job opening for their own to be keeping the Japanese workers only suited with their friends. 

Can anyone investigate on these organizations for any connection with the gang stalking?
