Rami-chan no Ooedo Sugoroku: Keio Yuugeki-tai Gaiden

After the first two battles with Dr. Pon Eho that did cataclysmic damage to Edo, things are starting to look normal again, and Rami Nanahikari, Pochi and her grandparents go to the beach, following a hot lead on more sacred treasures. Rami and Pochi swim off the beaten path to an abandoned shrine. After blowing up the ground and reaching the disclosed location, they reach a door with a powerful seal that they can't open. Just when they think that they are empty-handed, Pochi finds a ring with the same seal as the one on the locked door, which turns out to be one of King Solomon's Treasures, with the rest hidden somewhere around Japan. Rami now travels around Japan to go through all the leads on the rest of Solomon's Treasures, with Dr. Pon tracking her every move.
