Let's start on day 7. The killer overheard me, Nils and Takarou arguing over which sport to play. I don't know when the killer got his motive to kill, but one thing is for sure: The killer wanted to frame me for the murder by killing Takarou AND Nils (because i was kinda mad at them). The following morning, the culprit put his plan into action. The first one they killed was Takarou. The culprit saw him going to the museum, and immediately entered the museum himself. Takarou turned around and saw the culprit, who pushed Takarou towards the "Gone Fishing" statue. One of the fishing rods on the statue entered Takarou's abdomen, killing him, as the culprit quickly left.
Next up was Nils. Before the killer went to the kitchen, they first went to the tennis court, where Nils accidentally left his soccer ball, and took the soccer ball with him as he went back to the kitchen, where Nils was. The culprit stuffed one of the kitchen knifes into the soccer ball (with the blade sticking out) and tried to attack Nils with it. Actually, their goal was to scare Nils with it. Which worked, Nils walked backwards trying to escape from the culprit, and didn't notice the freezer was opened behind him. Once Nils was inside the freezer, the culprit closed the freezer and blocked the door using their own body. Nils tried to push open the door with all his strenght, but it didn't open. After making sure Nils was dead, the culprit took the soccer ball with the knife still in with them as they left.
Last on the list is planting fake evidence. The culprit left the soccer ball with the knife at the tennis court. I don't really know why, but maybe he was trying to make it look like the soccer ball was never used, or to frame me or something. Next, when the culprit was in the dining room with Syno, the culprit faked hearing someone running away from something in fear. Of course, there's no way that could've been real, which is proved by Willow's quote on day 9:
"Someone's been dead for 24 hours and no one found the body"
In other words, unlike everyone's been saying, Nils never found Takarou's dead body in the museum, therefore proven their testimony wrong. Also, i know that if the culprit is someone else, they could've run the whole time to make up a scene, but if that is true, i don't believe the person who i think it is was the only one who heard that.
You almost succeeded the perfect crime, but that one mess up gave it all away...
I have an idea for next time. If you don't want to use it, that's fine.
Albania suddenly declares war on Montenegro, which no one was pepared for. Serbia is Montenegro's friend, so he declares war on Albania. Bulgaria, who is Albania's friend, joins Albania's team and attacks both Serbia and Montenegro, but Instanbul (who is on Montenegro's team) attacks Bulgaria to stop him from doing so. Suddenly, Macedonia became evil, joins the war in none of the teams, and tries to attack everyone else in the war...
1: After failing the previous raid, Egypt, Mali, Rabat and Tunisia try to raid the Algerian Empire again, this time getting help from New Moroccan Republic (who helps at the fight against AE), Nigeria and Cameroon (who both make sure Niger and Chad don't try to stop the raid)
2: Tanzan Republic, Rwanda, Congo, Uganda and South Sudan are still fighting against the Democratic Republic, this time the Central African Republic fights on DRC's side.
