What are the protagonists who disappear in the animation?

Since childhood, we have seen many novels, comics and various types of film and television works. Of course, careful people will find that every work revolves around the protagonist. But we can't avoid some wonderful works. When we watched them, the protagonist had died or even disappeared halfway, and did not appear. So today I'm going to talk about some protagonists in the animation I found who disappeared halfway.

Dragon Ball

In the earliest cartoon Dragon Ball, Lan Qi was the heroine. In fact, she is a little sister of Wukong's team with dual personality, which you would never expect. Lan Qi's role in "Dragon Ball" is actually mainly to undertake some funny scenes in the play and make the audience feel happy. By the end of the Dragon Ball story, mainly bloody fighting, the role of Lan Qi disappeared halfway.

Hikaru no Go

Heian period's talented chess player Fujiwara Sasuke, as one of the protagonists in the animated film Chess Soul, has been appearing on the screen since he was summoned from the ancient chessboard by Shindou Hikaru. Of course, he always guided Shindou Hikaru to play chess, but when Shindou Hikaru gradually got rid of his rude temper, he also liked playing chess. At this time, Fujiwara Sasuke disappeared. Shindou Hikaru has been looking for Fujiwara Sasuke since his discovery, but by the end of the animation, FujiwaraNosai has never appeared.

The Legend of Qin

The animation "Bright Moon in Qin Dynasty" swept the country as soon as it went online. However, in the fifth part of this work, "Bright Moon in Qin Dynasty", Tian Ming and Yu Shao, as the two protagonists of this cartoon, never saw them again after a mirage adventure with Shi Lan.

I wonder what the people in charge of these cartoons think. It's so sad that an excellent character suddenly disappeared.
