By drinking this essence, you have obtained the ability to give life to dolls.
*Whenever they are toys, PVC figures, Figma, Acrylic Stand Figures, or etc, you can use them to summon the characters they are based on and have them serve you. The figurine will disappear once you do that. The character that comes to life will have all their memories, powers, abilities, personality, and grow to their original height from the series they are in.
*By touching a figurine, and consciously deciding to summon them, they will appear before in a bright light, with all their equipment available to them. The equipment doesn't require maintenance, and any weapons such as guns will have infinite ammo. If the characters require certain things to survive or their power needs a specific thing to use their power to the fullest potential, they will no longer need it.
*By default, anyone summoned by you loves you to no end. It doesn't matter what their sexual orientation they have, their personality, or if they are in a relationship with someone in the series they are in, they will see you as their lover. They would gladly sacrifice their life without any hesitation for you, and do anything for you. They also don't mind you having a harem. You can decide how they see you before summoning them, but at the end, they will always be loyal to you and can never even think of harming you.
*You have the skills and knowledge to make high-quality figurines of your own, but you must acquire the tools and materials necessary to craft them on your own. The dolls/figurines you make are great enough that they'd be highly sought after if you sold them, and not counting actual magic or schizotech they'd be the best out there.
*If a summon were to ever get killed, they will be reduced to a figurine for 24 hours and come back to life after that. But if they are killed in this weakened form, then they are gone for good unless you have a reliable resurrection method on hand.
*Yes, you can have sex and have children with them. They don't need to eat or sleep, but they can choose to do so if desired. They don't get sick or age past how they are depicted in the figure you used to summon them.
*The beings you summon typically come from dead end timelines that no longer exist, where things went so horribly off course from their source material that they don't even have an afterlife to look forward to anymore.
