Detective Club ~ Case 1 ~ Kidnapped Cheerleader by rainrain

The head cheerleader disappears right after recess ends, and due to everyone assuming that she's busy practicing on her own, nobody realizes until nearly two hours later. Luckily, she turns out to be unharmed, and is found fast asleep in the student council room. Case closed, right? Well, your friend seems to think that someone was behind her disappearance, and pesters you to investigate it. With her help, can you discover the culprit?

Note: Despite the setting being in a high school in America, I don't live anywhere near one, and so, there will be some inaccuracies.
