Jujutsu Kaisen 0 has officially dropped its first trailer, giving a glimpse of Yuta Okkotsu and Rika. But aside from these two, the preview shows a mysterious ring that seems to bind the lead characters.

The Jujutsu Kaisen 0 trailer prominently features a ring and it is the center of it all. So, what is this mysterious band and what does it have to do with Yuta and Rika?

The upcoming film will be adapting the special short story Tokyo Metropolitan Curse Technical School from Gege Akutami himself. This is the mangaka's first story about Jujutsu Kaisen before the official main series drops.

It then turns into a prequel, telling the tale of a mysterious guy named Yuta. Fans have had only heard his name in the past events of the anime adaptation's first season.

So, Yuta and Rika's appearance in the trailer is a big deal to many. However, the Jujutsu Kaisen 0 trailer highlights a strange ring that connects the two more than the characters, so what is it?

According to Comicbook, six years before the prequel's events, a young girl named Rika gives Yuta a ring as a birthday gift. She says it is an engagement ring and wants them to get married when they are older.

However, before it can happen, she suffers a tragic fate. When she dies, she becomes a Cursed Spirit and attaches to Yuta's body.

This only shows that the ring plays an important role in the story of Yuta and Rika. This band also helps him to channel his power.

By the looks of it, there are more elements about this ring that fans are about to see in the movie.

Meanwhile, the trailer also reveals the voice actress Megumi Ogata will voice the lead character of Yuta, Hype Beast noted. MAPPA Studio will be handling the film's feature animation, while TOHO will be working on its distribution.

It also shows a fuller and closer look at Yuta's new character design. Aside from him, other characters will also receive a major redesign, including Maki Zenin, Toge Inumaki, Panda, Satoru Goko and more.

Instead of continuing a second season, the franchise has announced the movie's coming. The change in their looks will also play an essential part in the series, as fans will now see Yuta in action.

Jujutsu Kaisen 0 will hit the theaters on Dec. 24 in Japan, though there are no words yet about its international release.
