The goal of The Toukaidou Gojuusan-tsugi is to guide the fireworks maker, Kantaro through 21 extremely difficult stages. The games difficulty may prove to much for Arino to handle, and in an effort to help Arino AD Tsuroka ends up showing the staff his "singing" skills. At the amusement center, Arino soon spots Namco's awesome Lucky & Wild but it's not really his speed so he persuades Kibe to play him in Puyo Puyo. The trip ends with Arino, Kibe and Tojima trying not to embarrass themselves when they challenge each other to some bowling. There's also the latest instalment of Ring Ring Tactics in which Arino finally receives correspondence from a high school girl. The Xevious Observation Diary hits the 10 day mark and a surprising new character appears in the score.
