丽贝卡·蓝色花园走访几近荒芜的格兰贝尔王国，并遇到了王国内唯一的人类居住者西奇，后者想和她成为朋友。

B-立方主拉比莉亚嘲笑丽贝卡的B-立方频道不入流，致使西奇情绪失控。随后，西奇拿到了正式的冒险者卡。

在诺玛行星上，时间倒退至50年前，而哈比和丽贝卡在此遇到了年轻时的瓦伊兹博士，他曾在很久之前救过哈比的命。

为了抢回皮诺，西奇一行人闯入了西维尔的藏身之处。然而，瓦伊兹却想趁乱将皮诺占为己有。

登上骷髅妖精号之后，西奇前去桥上对战艾露茜·克里莫森，想要从她手中夺取战舰。

焰宣布自己将投靠德拉肯乔。之后，另一个焰却突然出现，让西奇一行人震惊不已。

在红铁骑和西奇之间的战斗结束后，西奇一行人返回“伊甸星原”。他们不得不跟大家宣布一个坏消息。

"You've lived enough, time to sleep," says Shiki, who has reached Overdrive and defeated Drakken Joe. However, Weisz's anger does not subside, and he stands over and points his gun at the barely alive Drakken Joe.

Before they venture beyond the cosmos in search of Mother, the Goddess of the Cosmos, Edens Zero visits Granbell at the request of Shiki, where he has an unexpected reunion.

Edens Zero is cornered by Edens One and Shiki and the crew are saved at the nick of time by the space pirate Elsie Crimson. After the battle, Elsie boards Edens Zero and talks to Shiki about something Ziggy had asked her to do a long time ago.

With Laguna's help, Shiki and the gang obtain a hint for finding Mother and leave Red Cave towards the Verdant Planet Foresta. Meanwhile, Elsie's pirate gang, cruising through the Aoi Cosmos on the Skull Fairy, are being pursued by Justice of the Cosmic Government's Interstellar Union Army.

Now that everyone's back on the ship, Shiki introduces Xenolith, who has some disturbing statements that affect Shiki and his companions. Meanwhile, Oceans 6, Poseidon Nero's group, assembles and prepares for their next move.

Under Xenolith's guidance, Shiki and his friends receive VR "bondage training" to overcome decline of Ether levels when they are constrained. During this training, Ziggy suddenly appears and hurts Rebecca with gravity, infuriating Shiki and causing him to break out of his constraints.

After Poseidon Shura's "Judgment Day" declaration, Shiki and his friends decide to think of a way to counterattack. Laguna suggests an idea that will take Edens Zero to the desert of Planet Sandra.
