The Brother Who Came From Heaven - S2.E5

Sugata and Sohara travel to Synapse with the aid of Nymph. Sohara accidentally drops an object onto the world below which falls into the hands of Tomoki who fashions it into a pedal bike that transforms into a robot. At Synapse, the two humans learn new details about the New World while Tomoki relishes his time with his new toy to satisfy his perverse actions. Sohara later destroys the toy and a new Angeloid is revealed post credits.
