Second season of Nanatsu no Taizai: Mokushiroku no Yonkishi.

Jill Savelle—fiancée of the crown prince Gerald de Kleitos and known as the "Lady Goddess of War"—is being hunted down by the same country she swore to protect. Betrayed by her betrothed, she is framed as a traitor and imprisoned. In her last moments, Jill is filled with regret, but just as death approaches, she awakens six years in the past. This time, she will not be a mere pawn. Now as a 10-year-old girl, Jill resolves to escape her imminent engagement to the prince. To this end, she jokingly professes her love to the 19-year-old dragon emperor Hades Theos Rave, who will one day stain the land in blood due to madness. But against all expectations, he accepts! In contrast to the tyrant from Jill's memories, the Hades of this time is a kind albeit unfortunate emperor. Can Jill prevent Hades from descending down the same dark, villainous road, or is he bound to an inevitable future?

Second season of Rurouni Kenshin: Meiji Kenkaku Romantan (2023).

Five hundred years ago, the fantasy world of Alneath was torn apart by a war between magically gifted immortals and mortals armed with magical artifacts. The conflict came to an end when mortals' hero, Gram, slayed the Demon Lord Veltol Velvet Velsvolt. In 2099, the world looks a bit different. Alneath and technologically advanced Earth have fused in an event known as Fantasion. Immortals have been hunted down to near extinction, and technological implants called Familia allow mortals to use magic. As the new world slowly recovers, Veltol's vassal Machina Solege resurrects him in Shinjuku, a techno-magical city constructed in the middle of devastated lands. However, Veltol's magic is severely weakened, and his former ally Marcus has betrayed him. To regain his fame and magical abilities, Veltol follows the advice of Takahashi—Machina's friend and a professional hacker—to start an unusual career: live streaming. His sharp tongue and comically poor gaming skills quickly secure him followers, but to dominate the world once again, Veltol must first uncover Shinjuku's secrets and thwart Marcus' vile plans.
