Trying to fight the Heterodyne that appeared in Hokkaido has proven to be nothing but trouble, and now it looks like the team is in for more of the same. Not only is the Self Defence Force unable to join in the battle until the appropriate legislation has passed, but Akagi's new friend Ishihara has stolen his Dai-Guard access card! Still the team cannot stand idly by, and it falls to Aoyama to convince Arisa, an old friend from university, to help them find a way to lure the Heterodyne to Dai-Guard.
