Tenko woke up on the next day and immediately checked her Monopad, to see if the Team Objective had already been revealed. It hadn't, but there was only one hour and a half left before that happened.

So she left the room and went to the dining hall to see if she could find something to eat, since she was already feeling pretty hungry.

Upon getting there, she found Kaito, who had taken upon himself to provide food for everyone. She also found Kirumi, and joined her on the same table to eat, even though their meeting time hadn't yet arrived.

It was a pretty good time to recover from their stress after all the excitement of the previous day, and Tenko took it gladly, talking to Kirumi about the things they were proudest of being able to do with their talents.

In Kirumi's case, that thing was accurately predicting the existence of a certain bug that parasited certain species of rare ants, based on strange behavioral divergences between otherwise identical individuals from these species. Scientists had later discovered that bug based on her theories.

In Tenko's case, was the time where she found herself involved in a murder plot in the Ukrainian embassy, and she managed to figure out that no murder had actually taken place, and the whole thing was actually a plot by the Russian government to try and get some diplomatic advantage to cover for their malicious acts in Ukraine (that actually occurred just a bit before the Russian Revolution, and may even have influenced it).

Then the food arrived, and Tenko was forced to admit that Kaito was an extremely good cook. Worthy of the title of Ultimate Butler. Kirumi smiled at how reluctant she was towards admitting it.

Time passed fast while they were having their breakfast, and there were only thirty minutes left before the announcement of the Team Objective when they finished.

Since there wasn't much time left, Tenko decided that the best thing to do for them was trying to find out even more about how the game worked.

"I think we should try to figure out how the other challenge types work, since we've only seen puzzle type challenges until now." She said.

"I think that's a good idea." Kirumi said "What do you propose?"

"I think each of us should go find a challenge with a big time limit, one of the 'Task' type and one of the 'Collection' type, because those seem to be the most normal ones." Tenko said "'Game' type challenges mostly require opponents, and the 'Challenge' type ones give me a bad feeling, specially because of their placement." She sighed "Eventually we will have to deal with those too, but it's better to start with the easier ones."

"I understand." Kirumi nodded "In that case, I'll take the 'Collection' type. Collecting bugs is one of my better skills, and it could be useful for that."

"Then I'll take the 'Task' type. Let's meet back here when it's time for the reveal." Tenko proposed.

And so, the two went their separate ways, looking for safes that fulfilled the requirements.

Eventually Tenko found something she considered acceptable:

"Safe #23. Type: Task. Reward for Completion: 2000 Monopoints. Time Allowed: 6 Hours. Punishment for Failure: None. Open?"

Tenko pressed the button yes, and the safe opened. At the same time, her Monopad beeped twice. She looked at it, and saw that there were two new messages. The first was:

"Determine the number of Puzzle Pieces that have already been collected. Type in the number."

And the second was:

"You haven't collected a bingo card yet. Take one from the safe."

Tenko looked inside and saw the "bingo card". It was a paper-thin metal plate which had a grid of squares printed into it, as well as a sensor similar to the ones from the challenge doors. Knowing what it meant, Tenko brought her Monopad up to the card.

"Bingo Card recorded. Fill in the squares to gain special prizes."

Right in front of her eyes, one of the positions on the grid was filled up, and it was actually the center position. There was also another message from the Monopad.

It was a notification of what had just happened, and following it Tenko discovered that the bingo card had been put in her items folder. touching it showed an image of the card, and touching on the filled up square revealed a short line of text.

"Completed a Challenge Door"

The meaning of that was pretty obvious. It seemed like one could fill in the bingo card by completing certain achievements. You could get prizes for filling it up, and probably it wasn't just "fill up everything", but filling up certain lines, columns and diagonals. That would make sense, because having to complete 25 (the total number of squares) achievements to get anything would be too difficult, even if most of them were easier than the one she had.

Tenko wondered if everyone had the same achievements representing the same places in the grid. That would make sense, since it would mean there was another set of valuable information to be traded among the players.

Still, Tenko pocketed the bingo card and decided to focus on the Task.

At first glance, she thought it was far too difficult, since it would mean figuring out the actions of all the other candidates, and the reward simply wasn't worth it. However, she realized that there was another possibility to consider: The chance that she would be able to figure out which Doors had been completed just by checking them.

In fact, it made a lot of sense. That way, this would turn into a simple an easy task which still would give her some important information, and the Monopoints would just be a bonus.

Having made her conjectures, Tenko started heading towards the closest Challenge Door in order to check it. But she was intercepted by Kirumi on the way.

"Did you already get your task?" The Entomologist asked.

Tenko nodded, showing her the task and stating her thoughts on it, and also talking about the Bingo Card.

Kirumi nodded and looked thoughtful upon hearing what Tenko had to say, then she showed what challenge she had chosen.

It was Collection Type as promised. The rest of the features were almost the same as the ones from Tenko's safe, with the only difference being the reward of 3000 Monopoints and the time allotted being only five hours. As for what the challenge itself was:

"Put five different puzzles inside the safe. Then press confirm."

It was pretty straightforward.

"Hmm... This makes me think about how the Collection Type challenges will work. So far, the only physical thing we have access to are those puzzles. Plus, I'm sure there are secrets to those different types of mission that we will only be able to see after completing one." Tenko said.

After that, Tenko went into the forum and looked through the posts. It seemed like no one had bought Kokichi's safe, and there were also two other safes for sale, one from Kaito and the other from Himiko, they were all being sold by the same price.

"Buying those could be a pretty reliable way of finding easy puzzles to complete the challenge." She said to Kirumi.

"Yeah. But I think I'd rather try to get more puzzles myself, to get more information." Kirumi said.

Tenko agreed that it seemed like a good idea.

At that moment, both of their Monopads beeped with a message. Tenko looked at hers, and saw that the Team Objective had finally been revealed.

"Solve the Riddle of the Adamantis Puzzle during the Endgame"

"It looks like you were right." Kirumi said.

"And that also gives us some new information." Tenko pointed out "It doesn't seem like just collecting the Puzzle Pieces is enough, since there's apparently a riddle based around them. Also, there's something called 'Endgame', which I imagine will involve all the students gathered together, so they can share the Puzzle Pieces each of them found."

She sighed "But I imagine that it's not going to be as simple as 'everyone joining forces'."

"You mean that we'll be put against each other even with regards to the Team Objective?" Kirumi asked "But how could this be, if we all need to complete this to survive?"

Tenko's voice was grim "There's nothing to prevent a few people from monopolizing most of the Puzzle Pieces. Everyone needs to have the Riddle completed, but people with puzzle pieces would have an advantage in negotiation. What if they asked for Monopoints or other resources from the people without in exchange for revealing it? This is only the first round, so getting an early advantage is a thought that should have occurred to a lot of people."

Kirumi nodded, seeing the logic in that "So... We now have six days to complete both Individual and Team Objectives."

"We've only started." Tenko said "I bet the game will soon enter into a chaotic phase."

After that, the two separated to check on the Challenge Doors more quickly, and it didn't take long for Tenko to realize that her conjecture had been right.

"Challenge Door #4. Type: Task. Reward for Completion: 1 Student Profile and 10000 Monopoints. Time Allowed: Ten Minutes. Players Allowed: 1. Punishment for Failure: Loss of Sight. Open?"

That door had previously given the fourth puzzle piece along with the Monopoints, but now it was something else (A Student Profile? That was truly something interesting, but she would think about it later), that made it obvious that someone had already come and gotten the puzzle piece.

She kept checking her assigned doors, then went back to meet up with Kirumi again. The two shared their discoveries: It turned out that, besides Door #9, that Tenko had completed, Doors #1, #4 and #15 had also been completed, and their Puzzle Pieces had been taken.

"Those numbers sound familiar..." Tenko said, and focused "... That's right. Those were the Pieces needed to be able to open three special safes. Which must mean..."

She looked at Kirumi, who had already understood what the Detective was getting at. The two left together, going in the direction of a very particular safe: The one which had the requirement of having Puzzle Piece #15 in one's possession to be able to open. Tenko swiped her Monopad next to the scanner of the safe and heard it beep. She looked at it, already pretty sure of what she was going to see.

"This safe is locked. Do you wish to send a request to the owner?"

And it was exactly like she had imagined. She showed the message to Kirumi.

"I imagine the other two will be the same way. Isn't that right?" The Entomologist commented.

Tenko nodded. Then she took a deep breath and started talking:

"And there is another source of concern." She looked at Kirumi "I don't know who got this safe, but do you remember when I sent a message to you."

Kirumi nodded, and then froze.

"Exactly. My name was displayed on your Monopad. That means the owners know the identities of the people who are interested in their safes, and this disparity of knowledge is another form of power in this game." She sighed "Thankfully, this should only happen if I actually sent in a request, so there are no worries about that so far."

Kirumi put her hands behind her back and thought for a bit before speaking:

"You said the situation would become chaotic soon. And it seems like you were right."

Tenko nodded "This is only the beginning."
