Lolopechka initial introduction showed her to be clumsy, easily distracted, and somewhat absent minded. However, as the Princess to her kingdom, Lolopechka takes her responsibilities very seriously and cares greatly for her subjects as seen in her devotion to constantly protect and nurture her kingdom's lands for the sake of her people's prosperity using her immense power to singlehandedly protect the entirety of the Heart Kingdom and assist in its development by using her water magic on its forests and crops.
Lolopechka receives the curse of Megicula and has about a year before it kills her. When a group of Clover Kingdom Magic Knights request entry to the Heart Kingdom, Lolopechka and Undine decide to test the Knights' abilities. They sense Asta and his devil among the Knights. While the boat is traveling, Lolopechka kidnaps the boy and brings him to an underground chamber so that Undine can test him.
During the fight, Lolopechka falls asleep on her pet beaver behind the throne. Asta barges into her room and startles her, causing her to accidentally headbutt him. Undine pulls Asta away from her and comforts the Princess. Lolopechka explains that they were testing the Magic Knights, and when Asta asks about the curse they were following, the Princess reveals that she is the cursed one. Suddenly Lolopechka breaks off the conversation and rushes off to take care of various things around the kingdom using her Mana Zone. Undine dresses Lolopechka in her formal attire, and the Princess finds the clothes cumbersome and trips over them.
Once Gadjah has brought the other Knights to her palace, Lolopechka asks for their help but then trips and stumbles, dropping her regal demeanor. She explains the situation with the devils and asks Asta and Secre Swallowtail for the help of their magic. Noelle Silva and Asta contact Yami Sukehiro for permission, but he is too busy in the bathroom, which Lolopechka finds amusing. Mimosa Vermillion instead contacts Marx Francois and Julius Novachrono. The Princess and the Magic Emperor discuss the arrangement and agree to an alliance. She admits that they are all too weak to defeat Megicula, so she decides to have her Spirit Guardians train the Magic Knights for six months.
Six months later, Lolopechka spots on of the Spade Kingdom's Candelo moving through a Grand Magic Zone and using the weaker citizens to power it. When she tells Asta about it, he immediately flies off, so Lolopechka sends Noelle, Mimosa, and Finral Roulacase to help Ast and Luck Voltia and Leopold Vermillion to free the occupied town, Tolon. Noelle carries a copy of Undine to Tolon, and Lolopechka uses it to erect a barrier around the town.
When the Magic Knights return to the Heart Kingdom, Lolopechka compliments their efforts and dismisses them for the day. Luck, Leopold, and Asta want to spar with Gadjah, which Lolopechka finds exciting and wants to join, but Undine convinces the Princess to take a bath instead. She joins Noelle and Mimosa in Elmora Lake. Lolopechka admits that she is happy to have met good people from the Clover Kingdom and to have made friends with whom she can be herself.Later in her underground chamber, Lolopechka dotes on Charmy Pappitson, feeding her fruits. Her laughter is interrupted when she senses people infiltrate her barrier. She creates a map showing the intruders' locations and realizes that one of them is Vanica, the Dark Triad member who has Megicula.
