"Shiwa" (Wrinkle)
"Seasonal Feathers"
"Watashi no R"
"Alluring Secret ~Black Vow~"
Also these didn't make me cry but still recommending them cause they're still sad
"Leia"
"Just be Friends"
"Rolling Girl"
"Solitary Hide and Seek Envy"
"The Lost One's Weeping" (My go to song everytime school stresses me out)
"Sarishinohara"
"The h@nged girl in the haunted house"
"Secrets of Wysteria" (This was based off the serial killer Albert Fish's crimes)
"Alice of the Human Sacrifice" (this is horror but it's interesting so just recommemding. It's really catchy too)
Also, you should definitely check out the 7 Deadly Sins series of mothy, If you haven't yet. "Daughter of Evil" the prequel of "Servant of Evil" is part of it.
Seasonal Fethers is also known as "Feathers Across the Season"
Saigo no Revolver (part of 7 deadly sin series as gudetama's minion said)
