So, the OP theme of the anime will be called 「アイデン貞貞メルトダウン」 (IdenTeiTei Meltdown, Tei being the kanji for "chastity") and will be sung by a cosplayer called えなこ (Enako) and a YouTuber called P丸様(Pmarusama). Don't know who they are, but they seem like big deals.
The ED theme of the anime will be called 「ひめごと*クライシスターズ」 (Himegoto*Crisisters) and will be sung by the「ONIMAI SISTERS」which are just the seiyuus for Mahiro (高野麻里佳, Kouno Marika), Mihari (石原夏織, Ishihara Kaori), Kaede (金元寿子, Kanemoto Hisako), and Momiji (津田美波, Minami Tsuda).
