In the manga Shinya no Dame Koizukan (深夜のダメ恋図鑑), I spotted four different symbols (marked in red in the picture). The Ψ symbol is even repeated a few times, but I can't figure out what it means.
I've tried searching up Japanese symbols and have gone through Wikipedia's List of Japanese typographic symbols etc. but I can't seem to find the following symbols anywhere. What do they mean? Thanks in advance for your help!
Edit: They look like Greek, but from the context, I believe the speech should be in Gifu dialect and there shouldn't be any Greek used :(
