The manga that im looking for had a girl with short dark hair on the cover. Group of highschool students were in a ghost hunting club together. The short haired girl would sexually tease a nerdy guy in the group I think there was a chapter where she like gave him her underwear and peed on him or something?? LOL I cannot remember for the life of me.... There were 2 other students in the club one more jock guy I think and a extroverted 'popular' type girl with fangs ??

hi

Sounds like Sundome.
