Jikochuus (ジコチュー) are the main monsters of Doki Doki Pretty Cure! that are created by capturing the hearts of people that have thought of doing something selfish. The Selfish Trio can turn a person's heart black with selfishness if the person thinks even just one selfish or evil thought, while Regina can turn anyone into a Jikochu even without any selfish thoughts. They can be defeated with the basic purification attacks of the Pretty Cures. They are similar to the Desertrians from Heartcatch Pretty Cure! and can speak like them. Unlike the monsters of the previous season, they are not made with an object. When the heart is captured, it grows bat wings. The villain then allows the black heart to expand 3 times before it explodes and the Jikochuu appears. When the heart is taken from the victim, there is a black hole shaped like a heart in his/her chest.
In episode 27 it was shown that Selfish Deputies (in this case Leva and Gula) can combine their powers and summon a combination Jikochuu which has two times the size and five times the power of a normal Jikochuu. It is not known yet whether the Selfish Trio can also use this technique or not.
The Jikochuus are all voiced by Iwasaki Masami.
All Jikochuus have same adornments. They have yellow eyes with a black iris, a black heart with grey outlines and dark bat wings, and sometimes they have batwings somewhere on their body. Jikochuus are the kind of monster that is born from selfish thoughts. (Example: Cut-in-line in Japanese is"横入り" which is crab.) The color of the Jikochuu's body depends on who made them. Ira usually has blue and black colored Jikochuus, while Marmo has bronze and brown. When they are defeated, they turn black, their eyes turn to hearts and they say love three times, then they disappear and the heart flies back to its original owner, and the black heart in his/her chest disappears.
All Jikochuus have their own abilities and powers depending on what it is.
- The name of Jikochuu comes from "Egocentrism" in Japanese (Jikochuushin).
- The Jikochu's origins as manifestations of corrupted hearts reflect the Emblem-type Heartless of the Kingdom Hearts series.
- Like the Desertrians, they are created from peoples' hearts and speak the person's thought.
- The Jikochuus seem to do not have a generally voice. Though, they are voiced by the same person, their voices sound differently per individual.
- Just like Desertrian with a dark bracelet and Hyper Akanbe. The villain can transform into a monster to fight the Cures. If damage is taken, it will cause pain and anger and absorb its life to the users.
