Chapter Summaries

Chen Si, Erwin, and their companions discussed whether to seek peace with Marley before attending an Eldia assembly in Liberio. As the assembly began, Chris asked Chen Si whether she should marry him, and the venue plunged into darkness.

• All the lights in the venue went out, leaving only spotlights shining on the center.

At a Marleyan rally, the Eldia Merchants’ Guild president denounced Paradis Island, prompting Eren to slip away and Chen Si to follow. Chen Si later found Eren missing and learned from a newspaper that Willy Tybur planned a world address, leading the group to prepare to support Eren in the coming war.

After everyone dispersed to gather information or enjoy their free time, Chen Si asked Mike whether he wanted Chris to refuse to marry him.

• Chen Si told Erwin and the others he would pursue Titan research intelligence and deal with Marley’s Warrior Unit, while explaining that Philia’s Aunt Lisa might be a Special Operations Department agent.

Rundstedt brought Roald to Mogwin’s underground institute to test whether Roald’s blood could advance Marley’s army. Roald’s blood proved ten million times more active than previous Titan samples, leaving the researchers with a promising new result.
