Part 1: Investigation

From MC's perspective:

"We are going to enter Monster Zone. If you are free, you can join us," Laverne asked. Last time, Zack rejected their invitation. Since Michael is not here, she is hoping that Zack would agree.

"No," I replied.

"I have some other work to do for the time being. So I'll contact you when it's needed," I said 

Ernest frowned. But it can't be helped. They can't force Zack to agree. Then the duo left the dining hall.

Seeing they're disappearing back, I sighed inside. Actually, it would be fun to join forces with them. But I don't want to reveal my cards this early.

10 minutes later,

I walked out of the dining room. Then I took large strides towards the monster facility. Shortly after, I walked into the place. 

As usual I walked to the office to register. After registering the information, I waited for the tamer to arrive.
