Ep 1. The Seventh Spirit

The Third season of Date A Live introduces its first episode, "The Seventh Spirit." The episode begins with the protagonist, Shido, who is now slowly adjusting to his life after the previous seasons' events. Shido was a high school student until he discovered that his partial spirit powers allowed him to seal the power of spirits through romance. Now he lives with his curious sister, Kotori, who is also the commander of Ratatoskr, an organization that deals with spirit-related incidents.

As the episode progresses, Shido's peaceful life is disturbed when the past he left behind comes back to haunt him. A new girl, Natsumi, makes an appearance, and it is apparent that she had transformed herself into a deceptively innocent-looking person to deceive others. You soon learn that Natsumi is one of the most powerful spirits ever to exist, and she hates humans to the core.

Shido then sets out on a new mission to seal the power of Natsumi and save the world. This mission involves dating her to secure a "kiss" that helps seal the power of spirits. But since Natsumi has a grudge against humans, it is going to be a lot harder than Shido had initially anticipated. With the help of Ratatoskr, Shido plans his approach, eventually leading him to take the most drastic measures.

The bond between Shido and Kotori also deepens throughout the episode, unlike in previous seasons. After Kotori's secret is revealed, Shido decides to accept and embrace the powers he has been bestowed upon, and together, they aim to protect the spirits in the world.

As the episode progresses, you watch Shido team up with his previously sealed spirit, Tohka, as well as the other members of the Ratatoskr team, to try and save Natsumi and seal her powers before it's too late. "The Seventh Spirit" introduces new characters, such as Kurumi Tokisaki's doppelganger, who signifies a significant threat for Shido and his mission. The episode livens up with intense fight scenes between the spirits, who are battling to save the world.

Overall, "The Seventh Spirit" sets a high pace for the rest of the season with its intriguing storyline and intense action. It also introduces new characters and showcases the previous characters in new lights. The episode leaves viewers excited to see what will happen next and how Shido and his team will deal with the situation at hand.
