Tazuna and Koyori meet their next opponent: Kodama, a powerful idol singer who has defeated many other Hand Shakers. She and her producer are their toughest opponent yet, and together, they overwhelm Single Gear. Tazuna barely escapes into the water below a nearby bridge...

Tazuna and Koyori battle Awaza Kodama a second time, and she's just as powerful as the first. Tazuna, and Single Gear, cannot hope to defeat her. Their only choice is to rely on Koyori's unseen strength.

With the last of their foes vanquished, and Koyori now having the ability to talk, it's time for her and Tazuna to take up a part time job at the local Cocktail Corn. It's a time to reflect on what's gone on so far, meet old friends, and ready the pair for the future.

Tazuna and Koyori are facing off against Koyori's sister and the doc's old partner. Koyori's sister has been reduced to an emotionless mute after years of difficult treatments and abuse. Can the two of them bear to hurt someone so close to Koyori? And even if so, can they win against Handshakers who are so much more powerful and determined?
