Merci

Merci (Also known as ISDC5386292C4 Mainframe), this computer system can speak Japanese, as well as some English and French: it keeps saying "Merci beaucoup" and "Trebien" and calling Ginga "Monsieur Ginga". It works for Daidouji: Merci helped him gain data on Ginga, in order to eventually completely defeat him. It made Ginga believe that he was participating to a live TV program called Challenge Blader where he had to show his beyblading skills. Merci basically controls everything that is computerized in the Dark Nebula Castle, which includes more than enough systems and things.
