The first day

There are a total of 30 heroes summoned by the Blessed Church.

After arriving in this world, most of them were both puzzled and surprised. They appeared inside a spacious room. Beneath them were unusual marks and they were surrounded by four golden pillars with glowing imprints of golden color.

Upon seeing it, most of them thought that it looks similar to a sci-fi fantasy movie.

When they glanced around, they noticed some people were wearing unusual dresses. An all-white gown and a veil on their heads hid their faces.

About 16 people were surrounding them at that time. They screamed out upon seeing them, "Welcome, dear Heroes!" seemingly excited and celebrating for something. 

The puzzle group of students was flocking in the middle of the room. They were warily glaring at the people around them.

Amid the confusion, two students were able to remain calm and were able to ask a question to the person who stood up among the rest.
