Day 21[edit]
Go to the HQ and you'll see Hiruma. Talk to him and he sends you to the high school of the football team the Zokugaku Chameleons. Leave the school, and Sena will eventually return to it. Go up the staircase and you'll be on the second floor. Go all the way to the right of the second floor and you'll see an open room. Go into the room and tap the table with 
to the right of the chair. Sena will leave a paper on the desk. After this, he'll return to the Deimon High School and be back at the Devil Bats HQ. The day will then end.
Day 22[edit]
The day will start of with discussion. Today, you'll be facing another football team - the Zokugaku Chameleons. They mean business, and will not be going down easily. The player to look out for here is #42, Rui Habashira. He's the linebacker of the team and, if you choose Eyeshield to run with the ball to the end zone, he will likely come forth in a face-to-face confrontation with the speedy Devil Bat. If there's anybody to block from running to the end zone, it's him. Other teammates include #52, #62, and #9, all of which have no notable specialties. Beat the Chameleons and the day will end.
Day 23[edit]
Go to the Devil Bats HQ again. Mamori will be there, ready to give you a quiz. Take the quiz and then leave the HQ. Go to the entrance of the school, and there you'll see Ishimaru. He's ready to give Sena another paper route. Finish the mini-game (which is just an extended version of the first one he gave you) in a good time and the day will end.
Day 24[edit]
The day barely comes to a start when Rui Habashira of the Zokugaku Chameleons kidnaps Sena. Apparently, he isn't very happy that his team was beat by the Devil Bats. When you get control of Sena, you'll be in Zokugaku High School. Go to the second floor again and look for the Chameleons HQ. There, you'll find your kidnapper. Unfortunately, Sena doesn't get much of a word in, and gets kicked out of the HQ. Now leave the high school and go right for a mini-game. This one is as simple as it can get - run to the spot on the map, and then run back to where you started. With that, the day will end.
Day 25[edit]
The day will start with a talk between Sena and Monta. After this, go back to the Chameleon HQ and do the same mini-game over to end the day.
