Matsumoto and Hamada of comedy duo Downtown, invite fellow comedians Hamaguchi and Arino of Yoiko, to a friendly outing in Akihabara. Since Akihabara is the nerd capital of Japan Hamaguchi and Arino dress as Gundam characters for the occasion and the dress up certainly won't end there.
They'll be subjected to a variety of nerdy activities including more cosplaying at the hands of their cruel hosts as they attempt to befriend them and be declared friends of Downtown.
