Kai and The Mysterious Trials

The story so far revolves around a group of young superheroes known as the Spirit Saviors. The group includes Kai, Kazuki, Hana, Ayaka, and Ryujin, who possess various elemental powers. They have been fighting against evil beings and protecting the world.

Kai and Kazuki, who were vigilantes known as Blaze and Shadow, join the Spirit Saviors after returning from their five-year absence. They become close friends with the other members of the group, and Ayaka develops a crush on Kai.

The group faces various challenges, including a city turning into a living being and a powerful monster they nearly defeat. The Spirit Saviors repeatedly depend on Kai, Kazuki, and Hana's strength and skills to defeat these threats.

During a friendly battle between Amethysta and Ryujin, Ayaka's jealousy regarding Ryu and Ryu's connection with each other comes to the forefront. Later, in a bath with the other girls, Ayaka activates her water spirit powers due to the emotions she feels.

During Ryu's practice session with Kai, Ayaka and Hana try to occupy Kazuki and Kai, respectively, so that they can spend time with the men they desire. Ryujin watches Ayaka as she goes off, feeling conflicted about her own feelings for Ryu.

Throughout the story, the group's bonds are tested and strengthened, and they face new challenges together.
