The original cast will not be replaced, which means, we’ll be seeing Naofumi, Filo and Rapthalia reprising their functions. However, there is a possibility of introducing new friends and enemies in the upcoming seasons.
In the first part, we came to know about a teenager whose name was Naofumi Lwatani. He was a Cardinal Hero of the Earth sent out to fight with the alien species with three other teenagers, with each one of them having their signature weapons.
As far as the story of the second part is concerned, it is expected to take pace from quantity 12 because the original publication has 25 volumes. The story will be continuing from the last season, that’s all we can figure out till now.
Producer of the Anime, Junichiro Tamura said, Rapthalia being his favourite character will be safe from threats. During the trip, characters may leave, which will break the hearts of most fans, but eventually it will only help. Moreover, there will be more vigorous opponents than before.
