I got a cute heroine in a dating sim as my little sister. So, I raised her as preciously as I could. I gave her sisterly love, expensive elixirs, gave her endgame equipment, relics—you name it. ''Big sis... you must never leave my side. I will not allow it.'' Until one day, she turned yandere on me, and her eyes that were looking at me seemed quite different. On top of already being surrounded by crazy women... Isn't this too much? ***** What to expect: - No incest. - Protagonist (Female) x Love interests (Futa). - Pure harem, not polyamory. Release: 3~5 chapters/week. Advance chapters at: https://www.patreon.com/c/Kalliel035.
