Oku-sama wa Mahou Shoujo
- (AP, RN) Anime, from part 05. Sayaka's beginning to deal with love, and has self-esteem issues after she gets teased for being flat. It's not easy being a mahou shoujo, and poor Sayaka has to deal with body issues at such a young age! She realizes she can change her appearance to an adult to lure Kagura. Transforming into a pig-tailed young adult, her plan seems successful. Sayaka is very pleased Kagura didn't recognize her. Sayaka is trying to be an adult on the outside, but is so clearly immature, as she struggles with her desire to act older than she is. One of the themes that was consistently touched upon was the difference between age and maturity. Kagura apologizes for trying to kiss adult-form Sayaka, and admits he got caught up in the mood. Sayaka wants to confess her true identity, and is starting to wilt from maintaining her adult form for so long. Before fainting, she asks Kagura if he likes big breasts (since he likes full-bodied pottery). Kagura ends up having to care for Sayaka. Ureshiko secretly infuses Sayaka with enough magic to feel better, and maintain her form. Kagura gives Sayaka his cell phone number and Sayaka giddily accepts it, and tells Kagura that her name is Sayaka. Kagura realizes this name sounds familiar, but has to rush off - age secret

One Piece Film: Z
- (RN AA TF AP) 12/12.
The Modo Modo no Mi is a Paramecia-type Devil Fruit that grants the user the ability to return anyone and anything to a younger state. It makes the user a Return Return Human (Modo Modo Ningen), as eaten by Ain.
- Ain's return powers allow her to basically de-age anything in 10-year increments. She gets Nami to 10-ish, Chopper to reindeer pup, and Robin to 20-ish. The ARs are mostly offscreen though you CAN see Nami shrink out of her clothes. Robin just kind of gets a little bit shorter, with a touch of boob and ass shrinkage (which makes no sense as she would have been full grown at 20). They stay younger through the climactic fights at the end.
Zoro defeats Ain and her powers are cancelled, resulting in the AP RN scene. Unfortunately Nami's wearing something kind of heavy, but her midriff gets a lot of delicious detail that her T&A doesn't, and Robin, wearing virtually nothing up top, gets a BE/slight growth shot. The topping on the cake are the deliciously over the top sexy-growth-moans they make the whole time, especially Robin, who's usually cool and tame.

She asks the boy if he knows her true age. Kirito gets a message over her radio to tone down the blasts since it's disturbing everyone in Hell and Heaven.

- Young adult man having love problems is approached by elementary schoolgirl as the reincarnation of his deceased Mother. It's a secret. Can this count as regression if said person retains their previous life memories? With that premise, only if the manga has side by side comparisons of the shoujo doing something that reminds him of Mom, then you could argue poof AR.
I have enough of a headache labeling breast expansion, progression, growth, and ass expansion on Sad Panda, then dipshits start thinking inflation belongs... Reincarnation (with memories intact) arguably counts as body transfer, not AR. Kyoukai no Rinne had it from Rinne's mother, and she retained her memories as a shinigami (she is a 5yo kid but still treats Rinne who is 15 as her son)... There was also Kurama Youko reincarnated as Minamino Shuichi from YuYu Hakusho, but the only AR was Juri in the Ura Urashima vs Kurama episode.
