The second chapter of the Haze Reverb × TV anime Chained Soldier Season 2 collaboration event went live following maintenance on March 23, 2026.

Second Chapter Open — New Players Can Still Join
The ongoing collaboration event, "Dancing Among the Dead in the Space Between Worlds," has entered its second chapter, bringing the story to its climax. Stia's giant form traps allies in a dream world, while squad leader "Yamashiro Koi" makes her entrance. Her decisive strike and the navigator's rallying call bring the team together for the final battle, all presented in full voice acting.

Players who join now can still obtain up to four collaboration characters for free through event progress and login bonuses. Completing second chapter missions also grants one random character — either "Emishi Yakumo" or "Kamiunten Mira."

About TV Anime Chained Soldier Season 2
Mysterious gates have appeared across Japan, leading to an alternate dimension known as the "Demon City," where a peach exists that grants special abilities to women only. A female combat unit called the "Mato Defense Corps" was organized to fight the monsters known as "Shuki." High school student Yuuki Wakura stumbles into the Demon City and is attacked by a Shuki, only to be rescued by Kyoka Uzen, the beautiful squad leader of the 7th Squad. Transformed into a slave by Kyoka's power, Yuuki awakens his strength and joins the Mato Defense Corps as a slave and overseer.
