Imma little confused, can someone explain the story a bit please?

Hum so...
SPOILER till c6!!!!









SPOILER until chapter6!!

An exorcist predicted Ryujin (dark hair) ‘s family disaster if they kept him. They did so they died in a fire. The exorcist sent him at a school of exorcist afterward. On the way he met Imae (blond hair), a mysterious boy who keep following Ryujin for unknown reason.

In this world, exorcist work in pair. One that can physically fight the demon (imae role) and one that can seal and banish them (Ryujin role). So both were put into a pair as they arrived together and have compatible power.
Though it seems that they failed the exam to become full fledge exorcist 3 times, it seems that it was just because their power can’t be evaluate the traditional way.
In the end the minister of the central exorcist made them pass a special exam and they become real exorcist on their way to their first mission.

Ryujin seems to be pursuit by a demon since birth and can only keep it away thanks to a charm the first exorcist he met gave him.
Don’t know what it is and both MCs have unclear origin (one with unknow past and one with unknow nature)

Thank you!!

Hope it helped (=・ω・=)
