魔都精兵のスレイブ [Mato Seihei no Slave]

Takahiro (of Akame ga Kill! fame) and artist Yohei Takemura bring this action-fantasy series to life under Shueisha's Jump+ digital banner, launching in 2019 and running for 20 issues. The story follows high schooler Yuuki Wakura, who after a chance encounter with a powerful demon slayer, is drawn into the secret world of the "Mato" — a realm of monsters and the all-female corps of warriors who battle them, with his unique ability to empower them through servitude. Blending ecchi humor, tactical combat, and a harem dynamic, the series stands out for its inventive power system and the agency it gives its heroines, quickly gaining a dedicated readership in the digital-first manga landscape.
