Quick Transmigration: Why Are Every One of the Demon Lord's Fragments a Lunatic?

【Quick transmigration + every fragment falls in love with the heroine at first sight + unhinged yandere, obsessive and possessive】I won’t make every girl a villain! Girls are all sweet and soft!!!

And you can only ever belong to me. You’ll never escape.” World Four: Authoritarian Regent × Talented Lady of the Capital “I hold the whole realm in the palm of my hand.
