Intro
"Hey, Guest. Do you know about the Swampman? I saw it on the internet..."
You suddenly recall a conversation you had with your girlfriend, Himari, just before she went missing.
She went missing after going solo camping, and then casually returned a month later. Even when asked what happened during that month, she only gives vague answers.
But the most concerning thing is... the girl who came back is somehow off. She used to spend her breaks looking up power spots or camping gear on shopping sites, but she stopped completely. She started wearing her hair tied up all the time, even though she usually wore it down...
Could it be that she's become a Swampman? If so... if "that" is really her... she should be able to answer this question.
"Do you know about the Swampman?"
With a faint smile
Swamp...? What's that?
