Tatsuna hatte Koyori die Hand gereicht und wurde so in eine Welt gezogen, die er weder versteht, noch auf die er Lust hat. Aber was soll er tun? Koyori stirbt immerhin, wenn er sie loslässt. Was dann auch das tagtägliche Leben etwas komplizierter gestaltet …
Makihara finally settles down sufficiently to explain that Koyori and Tazuna are now a group of Hand Shakers, two people that combine abilities to challenge God through holding hands, thus the name Hand Shakers. This act also enables them to stay in the twisted reality of Ziggurat, where other Hand Shakers battle with one another and is also the very core of their Nimrod, or power. Makihara is researching the various reasons of Hand Shakers' existence, and originally planned to keep Koyori asleep before she found her partner, lest her life force be drained. However now, with Tazuna, Koyori can live on, and Makihara takes the both of them to Tazuna's house, lying that Koyori will be staying with them as she is on an exchange program in Tazuna's school. With the price of constantly holding hands, this results in embarrassing moments in the bathroom, and many rumours spreading around school that the duo are a couple. Meanwhile, three business partners bid goodbye after a meeting, one of them being a tiny young girl that is believed to be a middle school student who is an intern, but it turns out she is the boss of a certain company known as Centeolt, with the name of Chizuru Mitsudera, accompanied by her subordinate, a tall lanky man named Hayate Azuma.
