Captain of the Juken club, Maya Natsume is one of Tenjou Tenge's leading protagonists. Normally, she is one to don revealing clothing and holds no qualms revealing her undergarments to anyone in the vicinity. However, in order to save on Chi, Maya spends most of her time in her child form.

Maya is just as confident in her child form as she is in her adult form. It seems that no amount of bodily limitations are enough to stop her beating the snot out of some delinquent punks!

Nezuko is somewhat of an exception to the others on this list. Where the others appear to either age up or age down at any given moment, Nezuko only alters her body size. Forced to spend the daytime hours inside of Tanjiro's backpack lest the sun ends her life, Nezuko's body must shrink to accommodate the enclosed space.

Nezuko is adorable in either form but her chibi version is particularly cute. Watching her run around with her oversized sleeves flapping in the breeze is a nice change from the blood bombing demon that we've seen fight alongside he brother.

Shinobu is one of the rare changing girls with three forms as opposed to only a child and adult form. Shinobu's base form is that of a child. After losing her powers, she is forced into this form and spends her days inside Araragi's shadow. However, as the story progresses, we also see Shinobu's teenage form and, ultimately, the full-strength Kiss-Shot-Acerola-Orion-Heart-Under-Blade that strikes fear into any man's heart.

Shinobu's child form holds very little power and spends most of her time pester Araragi to take her to Mister Donuts. Her older forms, however, see Shinobu as much more confident. It appears Shinobu's mind alters alongside her body whenever she transforms.

Umaru doesn't technically alter her form through some sort of mystical power. Being the perfect student all day every day can be tiring and so, when Umaru returns home, she dons her hamster hoodies and proceeds to lounge about the house like a lazy otaku. Umaru's shift from teenager to chibi is more of a metaphor to show her regression when relaxing next to her brother, Taihei.

Umaru becomes insatiably annoying in this form as she orders her brother to complete various tasks in her stead. She also proves that she knows how to have fun which she rarely expressed during her schooldays. However, despite putting up with each other's failings, the two share an inseparable sibling bond and will always be there for one another.

Jahy is the popular protagonist from the recently released Summer anime, The Great Jahy Will Not Be Defeated! After a magical girl destroys her homeworld (the demon realm), Jahy is dropped into the human world and forced to work as a waitress for a living. She spends her days struggling to pay rent and bickering with her landlord while searching for several crystals that will allow her to regain her strength.

Jahy's crystals are the source of her power. She uses these powers to transform from her child form into the bodacious Demon Lord's assistant that she is renowned for being. While more confident in her adult form, Jahy is still just as playful, silly, and argumentative as she is in her child form. With only two episodes of The Great Jahy Will Not Be Defeated! having been released as of now, we are looking forward to seeing where her shapeshifting journey will take her!

Another shifting beauty, Carrot is initially presented as an antagonist in Peach Boy Riverside. In the first episode, she unleashes a viciously powerful beam from her eye which destroys a large portion of the town Sally is exploring.

It seems that, when using this incredibly strong beam, the toll it takes on her body is too strong and this causes her to shrink down to her chibi form. This effect only lasts for a few minutes however and Carrot is raring to go in her adult form soon after!
