Arc 4Memories and Rising Seas
Xingsu helped expose Valerius’s criminal network while reconnecting with Clervie, whose memories he restored and later traded to Lin to bring her back. As Fontaine’s sea continued to rise, he learned the truth of Furina’s role and set out to solve the prophecy, leaving Clervie restored to the House of the Hearth.

- Xingsu uncovered Valerius’s L㏒s operation, joined Arlecchino in confronting the threat, and led an undercover raid on Valerius’s mansion as Morning Star.
- Lyney and Lynette escaped Valerius’s mansion, while Clorinde and Chevreuse raided it and investigated Valerius’s apparent suicide.
- Xingsu helped Clervie recover her memories, and she reunited with Arlecchino before Xingsu and Arlecchino spent the night together.
- As Fontaine faced the rising sea, Xingsu met Furina and used her memories to learn that she had impersonated the Hydro Archon for five hundred years.
- Furina broke down over her inability to save Fontaine, and Xingsu left determined to solve the prophecy.
