the order the chapters for this web novel came out are really confusing and i can't seem to find the first chapter. https://www.novelupdates.com/series/yuusha-party-no-kawaii-ko-ga-ita-no-de-kokuhaku-shite-wn/ Yuusha Party no Kawaii Ko ga Ita no de, Kokuhaku Shite Mita Help?
there were never any c1 translation of web novel, iirc. HaruParty, (the link @Wannabe-shutin give above) started directly with the Light Novel version instead of web novel.
from what i remenber its was translated by re:Translations and its on a google drive fond this link on re:Translations https://docs.google.com/document/d/1rhoCQcOUW1eccV4Fsh6K76u0Vup7DMQhBfDcknEbFHI/preview
