22XX
- (AP, AR, age stasis) Shimizu Reiko manga. Serialized in Hana to Yume, published by Hakusensha, 1994.
2 androids named Jack and Elena have passed the centuries unaging and eternally beautiful. Jack accidentally gasses a young cannibal. She transforms into an older, seductive woman named Ruby. Photrisians (Foturisu-jin) switch between a normal day form and a night form to entrap victims to be eaten. This engenders a change in age, thought patterns, hair length, and all other aspects. Jack and Ruby switch between dangerous encounters and light comedy as the adult Ruby attempts to seduce, kill and eat Jack and the child Ruby awkwardly deals with the aftereffects of her predatory other half. The sex and action is interspersed with exposition of Ruby's past. Jack describes her as a young girl by day and a prostitute by night. The reason behind Ruby's transformation is that she must attract people to eat, selling herself as a desirable woman. Ruby's adult side is the inherently forbidden sexual side of the child Ruby, and the more wonderful self she has been longing for. Adult Ruby represents not only sexuality but also action, initiative and life-and-death power. The younger Ruby is a study in passivity, awkward and childish, and avoids physical contact. She is in all senses a child- dependent, indecisive and powerless. Jack's behavior towards Ruby changes with her appearance. At night, he is her willing sexual partner, playing the inexperienced young man to her artful seductress (adult Ruby licks Jack's neck and back, to his dismay). During the day he is paternal, catching her food and saving her from accidents.

31 Ai Dream
- (rejuvenation ARs, reducing RNs) 2022, penultimate chapters.
A secret medicine gave 31 y.o. businesswoman Chikage a new, chemical born alter-ego: the teenage Akari!
This duality has made jaded Chikage's emotional life far more complex. She is drawn between two friends on each side of her new nature, with complex feelings for the man who gave her the medicine.
A side effect is that every reversion is making her adult form slightly younger than before. Her complexion is softening, her hair longer and more vital, and she no longer needs her glasses.
This poses an existential problem for the overmighty duality she has created. Younger and younger upon each reversion into the adult Chikage, her adult self will eventually cease to be, leaving only the form and name of teenage Akari.
Chikage must choose between her renewed life as a corporate professional, or the vibrant teenager with her eclectic stardom. The conceit of her adult success is jeopardized by the growing primacy of her younger alter-ego...
Then Chikage discovers that she is running low on the medicine she needs to rejuvenate. Her personal and emotional heartstrings are caught between two selves and their respective worlds.
The mangaka Arina Tanemura may have perused Jekyll & Hyde at some point. She has promised a resolution to this remarkable story come 2023.

"Legend of Maidens", a group of high school shoujos in a psychics club, and their overseer Youko are convinced the world is ending. They summon a demon as their servant to avert the apocalypse. The club leader attempts to sacrifice another girl, but a demon transforms her into a baby. The demon is slain, returning the girl to normal off-panel; she is last seen trying in vain to explain to her parents that she was turned into a baby.
It's rather quick but does have process, as you can see her shrink into her clothes, ending up as a baby on top of her oversized outfit. A shame the OVAs never reached that point in the manga, I would have loved to see this bit animated!

Vended already posted AR from the manga and anime, where a boy is trapped in a villain's time-reversing technique and slowly regresses to infancy. Another AR later on only goes to childhood, but lasts much longer.
In Ch173, Kannagi (guy), Kotoha (girl) and 3rd dude are regressed into kids by the villain Isora. They go through lots of tough stuff then. In Ch187, the AR is finally cancelled, and they returned to normal.
- No process, sadly; it's treated as a twist and cuts away before we see anything. Fortunately, it does leave them in oversized clothes, and looks pretty cute.

Are You Alice?
- (male ARed poof to baby) "Anata wa Arisudesu ka?" by Ninomiya Ai, 2012. Ch25.5.
No freaking clue what the plot is, but Alice (who's a dude BTW) transformed into a baby after eating a piece of mushroom from the human Cheshire Cat. It happened off-panel, but leaves him in oversized clothes. There's also a much weirder male AR cutaway at the end; an anthro fish butler eats part of the same mushroom, and in a bit of dark comedy turned into a flopping tiny fish before perishing. A female character briefly discussed eating that mushroom, but to my annoyance nothing came of it, and it merely adds to the confusion. Still, the first AR is pretty cute, though I'm a little annoyed it's male; the name made me think "Ooh, FINALLY found some female AR!" but nope, it's still male because the name Alice belongs to a guy.

Arifureta Shokugyou de Sekai Saikyou
- (male TF maturation effect, muscle boost) "From Commonplace to World's Strongest".
Light novel by Ryo Shirakome, Takayaki. Anime: 07/2019 - Average male teen Hajime Nagumo was transported to a magical world. Ep01 presents a hunk treatment scene. His body got toned, and he gained a hoarser voice, implying that he was slightly matured. This surely opens the possibility of seeing the shoujos being TFed later on.

Vol 4 manga: Chidori, an elementary school kid, is visiting Aya, Suzumi, and Yuuhi. She has C-Genes. When she transforms, a change in her cells appears. She completely conforms to her new shape and now looks 16. She mainly gets taller, gets bigger breasts, and her hair grows and darkens. She pretty much has the power to change into this form at will (though her clothes are always ruined after she does!) With her changing form she can't lead a normal life. She discovers her power when one of the other patients at the hospital was attacking her little brother. Everyone practically fainted in disbelief when she revealed she was 16. She's in high school! The tennyo drug made her seem younger.

Bikkuriman
- (AR OC, some OA'd) 1987-89 anime series, Ep33.
Monster of the week is a weird-ass stroller demon, whose baby rattles transform people into animated babies. It gradually regresses most of the heroes into infants, leaving a few to kick its ass. In a dream sequence near the end, the villains hypnotize Yamato into thinking he's an old man or something; this illusion is quickly dispelled, and you see Yamato "age back" to normal. Needless to say the rest of the team turned back as well, though offscreen in most cases.
All ARs have oversized clothes, though process varies. The first AR is male, with old god Shaman Khan as the victim. It happened offscreen as he fell off a cliff onto a branch, and he is revealed to already be a baby in oversized clothes when the others pull him up.
The second AR has (I think) two boys and a girl as the victims. This time we get to see them shrink into their clothes, though the process is partially blocked by Yamato's dumb ass getting in the way. Fortunately he doesn't hide a lot, and it's still well done.
One of those victims is RNed back, then ARed into a baby again alongside another guy later in the episode. This third AR is offscreen too; the villains throw and detonate the rattles like grenades, and the characters are shown as babies.
Finally, Yamato's and the others' dream OA is also offscreen, though limited male face RN was shown as mentioned. All in all, a surprisingly great find IMO; I expected to see just poof ARs of one guy, but we get several ARs in baggy clothes of a fair number of characters, with one process.

She gets away from the goddess and befriends one of Keita Tsuwabuki's imouto, little Mika. Ichiko-chan spends the rest of the episode as a little girl with Keita's family to avoid Momiji, dealing with the issues of being treated like the child she appears to be, and unsuccessfully looking for a way to reverse the process.

An "aging box" is procured for her by the dog god Momoo Inugami. She thinks seriously about remaining a child and living with Keita's family, but eventually decides to return to age 16. It takes Ichiko a while to get over the experience of being part of a family as a little girl, and go back to her noisy teenage personality. Will there be more transformations going forward? We can only hope.

Black Butler: Ciel in Wonderland
- (male AA poof APed, male AR AA poof, RN) Kuroshitsuji series. S2, 2nd OVA Ep04, 2010.
Alice in Wonderland is one of the best standbys to sneak progression/regression into anime and manga (which is why I wish they used this kind of story more). Dressed in a pinafore, young male Ciel essentially goes through all the weirdness of Wonderland in a 2 part OVA, much like Ep13 of Ouran High School Host Club, where a majority of the main and recurring characters play roles in Alice's story. Ciel meets with the equivalent of the Caterpillar. The mushroom is personified by a woman with big breasts, where sucking on one side makes you older, while the other breast makes you younger. You see the results of this, but it's pretty much flash TF. I do think there's enough there for the imagination, unlike some other poof AP/AR's.

When the woman comes back for a checkup, he introduces her twin sister, but she rejects the little girl. In the last scene, the woman drives away while the girl leans against Black Jack and sobs. In the stories that follow, Pinoco stays on as Black Jack's assistant. She introduces herself as Black Jack's wife; although she looks like a child, she is legally 18.
