The second season of the anime Chained Soldier has released a brand-new trailer that teases the upcoming YOKOHAMA BATTLE Arc, spotlighting the arrival of a powerful new character voiced by Ami Koshimizu.
The trailer introduces Kuusetsu, a beautiful and threatening god who is a key player in this arc. She will be voiced by Ami Koshimizu, whose credits include Sailor Jupiter in Sailor Moon Crystal and Lufas Maphaal in A Wild Last Boss Appeared!. Kuusetsu is depicted with an elegant yet menacing aura, her presence immediately commanding attention as she interacts with the battlefield and other characters. The footage showcases intense combat sequences, strategic maneuvers, and moments of high tension, particularly involving members of the Demon Defense Force such as Mira Kamiunten. These glimpses build anticipation for the larger-scale confrontations and character developments that define the YOKOHAMA BATTLE Arc.
A character art has also been shared for Kuusetsu:
Chained Soldier, also known as Mato Seihei no Slave, blends high-energy action, fantasy elements, and distinctive ecchi themes. The story centers on Yuuki Wakura, an ordinary high school boy who becomes embroiled in the supernatural conflict surrounding Mato, a dangerous otherworldly dimension. Since its premiere on January 9, 2026, Season 2 has continued to air weekly, with episodes available for global streaming.
Produced by Studio Passione and Hayabusa Film, the series has maintained its reputation for fluid animation, creative fight choreography, and an unusual power system that ties abilities to the consumption of special “peaches” found only in Mato—abilities granted exclusively to women.
The core premise of the series revolves around the emergence of gates to Mato, the so-called “Demon City,” decades ago. These portals brought both monstrous threats and a rare resource: the peaches that grant superhuman powers, but only to female consumers. This gender-specific phenomenon led to the creation of the Demon Defense Force, an elite all-female organization dedicated to defending Japan from Mato’s dangers. Yuuki’s accidental entry into this world and his subsequent role under Kyouka Uzen, commander of the 7th squad, introduce complex dynamics of loyalty, strategy, and power exchange that drive much of the narrative.
Decades ago, gates to an otherworldly and dangerous dimension known as Mato-the “Demon City”-appeared across Japan. Those who partook in the “peaches” growing there gained unique abilities-but only if they’re girls. When down-in-the-dumps high school boy Yuuki Wakura finds himself caught up in a gate, he’s saved by Kyouka Uzen, the beautiful commander of the 7th squad of the Demon Defense Force, who…orders him to become her slave?!
This description from Yen Press encapsulates the series’ distinctive setup, which continues to fuel its appeal through a mix of intense battles, character-driven drama, and unconventional relationships. With the YOKOHAMA BATTLE Arc now being highlighted in Season 2, the introduction of Kuusetsu and her voice actress Ami Koshimizu signals a major escalation in stakes and spectacle as the story pushes forward.
Chained Soldier Season 2 is available for streaming on HIDIVE, where it is offered in an uncensored version with English subtitles. New episodes are released weekly following the Japanese broadcast. Availability may vary by region, and some platforms or services in certain territories might offer access through partnerships or channels.
