Toshi Densetsu series
- (demon AR AA poof) 5/27/2016 sequel to "Toire no Hanako-san".
UNREAL ghost-themed sex hentai compilation by the same author. The new character appears based on Sadako, a Japanese ghost with long black hair popular for crawling out of your Tv. She seems to be an online porn star who emerges from a computer porn the protagonist is watching, and shifts her appearance from a high-schooler to a younger loli (around the age Hanako was in the beginning of Ep01) to match his fetish while filming it for her own.
Only one AR and no RN AP. The appearance of the adult form is too short, she doesn't even get to have sex at that age. The anime may offer more detailed process.

We see 2 poof-like ARs of main characters... and sadly, one seems permanent. At the start the effects of the attack have already taken place. This is the AR with the most RN potential. At 10:10, the villain (who turns into a secondary character) suffers the aforementioned permanent poof. Since she appears in the opening in loli form, it's safe to assume this AR will be permanent. The episode features a large-chested yokai as well... so we may see several ARs throughout the anime and maybe RNs... all we can do now is wait - (The AP Ninja)

"If my wife become an elementary school student". An office worker and his cocooned daughter re-encounter their reincarnated wife and mother who died 10 years ago. The process of recognition is simple but accurate, telling secrets, vows, and occasions never mentioned to outsiders. Although the elementary school girl recalls previous lives, she also has another identity with her own family. She appears precocious due to her memories, showing a uniquely intelligent appearance in class. The straight-ball man is unwilling to let her go again. While he and his reborn wife disturb the emotional shackles of their shared past, their future may not be smooth. Ignore her? Keep a distance? Or wait for her to reach legal age to marry her back? This is the beginning of a miracle and trial. A female colleague becomes curious about the private life of her widowed male co-worker, who has an ambiguous relationship with a 10 y.o. girl. A complex drama.

Princess Hydra is pursuing Princess Walkure. Akina binds her power and in the process, Hydra is transformed to a small shoujo with light green hair. Whenever Princess Walkure and Kazuto kiss, Princess Walkure transforms into her true form. The AP transformation is very revealing, showing her totally naked a la Sailor Moon, but filling out to dimensions that would make the sailor senshi blush for modesty. Hydra's transformation is similar, but she is clothed. Walkure's sequence focuses on the growth of her breasts from non-existent to very round, complete with nipples. Then there's a shot of her buttocks, and finally her feet. Gradually she is clothed, first with shoes, then with hand gloves, and finally with an outfit. Akina was also returned to a child. (Akira)

Minamoto Koichi (the guardian of 3 powerful 10 year old ESPers) is hypnotized by Hyobu Kyosuke into believing his charges are sexy adults. Everyone else perceives the girls at their normal ages. We see Minamoto's and others' perspectives. Their actions as children are fine, but send different signals as women. Poor Minamoto must not let Shiho touch him, lest she know how he sees them. When The Children learn the truth from Kyousuke, they try to get their guardian (who they have a crush on) to treat them as adults. He snaps and yells at them, which makes them cry. The hypnotism wears off, and he sees The Children AR back to 10. (Tuxedo Will)

Antagonist of Black Phantom group uses ESP talent to zap protagonist Koichi Minamoto in his sleep. He wakes up believing he's 12 years old. At B.A.B.E.L. Headquarters, antagonist Major Hyobu uses his ESP power to make everyone else see Minamoto as a 12 year old. Koichi's body outside of the illusion remains fully adult. At 12, Minamoto gets a chance to interact with our 3 ESP preteen heroines as a peer, instead of their supervisor/guardian. Hyobu arranges for Minamoto to attend the girls' 5th grade class , without the other students thinking anything is awry. Minamoto's AR remains in effect throughout the episode, and the trailer for #50 shows him continuing his second childhood.
It is no problem for the girls to apprehend the perpetrator Esper even as their mammaries breach their uniforms. FF/AP scenes of the 10 year old girls remain a possibility. There were many flash forwards of the girls to age 20 in previous episodes.

Zettai Muteki Raijin-Oh
- (AA growth) 1991 anime.
A 5th grader and her friend get measured. The friend is happy to see she grew a couple of centimeters, but the main girl hasn't grown at all. Some older girls tease the main girl for being short, and she fears she'll never be tall. At night in her room she is fantasizing about growing up to be tall and strong. Another fantasy about an older and taller version of her has a guy confessing his love to her, and they embrace. She's praying and praying and praying to be taller. She goes to bed when the monster of this episode decides to use his height measuring tool on her. We just see a close-up of her face, smiling in her sleep.
The next day, we only see the outside of her house but we hear her exclaim in surprise at herself. Initially she was 115cm or around 3'9". The monster's first growth seems to cause her to be something like 5'4". At school everyone is surprised.
The Principal is saying good morning, and she walks past and is so tall he only comes up to around her elbow. She's now as tall as the middle or high schoolers, nearly as tall as the charkboard. She's going around flaunting it, so proud of herself, and goes so far as to pull one of the older boys by the arm and flirt with him. She is now slightly taller than him, and the guy is trying to hide that he likes it.
Later on we see her playing jump rope with her usual friends, but she catches her foot on the ropes, and it seems she's having a harder time at her height. One of the main guys (now significantly shorter than her) teases her, and she gets pissed and puts him in a full nelson. Since she's as big as everyone here, it should be ok for her to be at the command station.
Then the monster enlarges everything that he had previously grown, including her! She destroys her classroom and grows out of the building, and, after getting over the panic of becoming around 15m, ends up fighting the monster.
Afterward, the giant robot does the finishing move, and everything shrinks back to normal. She learns her lesson to wait until she gets older to grow, but gets teased a little bit anyway at the end.

A cross between a bird and a dragon, tatsumis take on the form of whoever they set their eyes on first so that they will be loved. Resembling a miniature Natsume, it will return to its original form after growing for a certain length of time upon leaving its nest. Natsume reveals the little clothes he has sewn for the baby. They don't fit too badly, but they have yet to know what it eats.
The next day Natsume finds his room in a very messed up state. He wonders if Nyanko had tried to eat the baby, but finds it has built a vase-like nest out of paper and wants Natsume to go inside to play with it.
Each day, Tama grows a little bigger. It declines to eat because it doesn't want to grow up and leave Natsume.
He is startled when a rodent runs past him. It turns out to be the youkai monk Isotsuki here for the baby. Nyanko tries to stop him, but ends up being sealed before he can transform. Natsume runs off with the baby into the forest. Isotsuki catches up easily and tries to take the baby by force.
Out of anger, Tama grows up to full size, seizing Isotsuki. Nyanko explains it has lost its senses by growing up so suddenly. Natsume pleads Tama to release the rat youkai, but it seems the shock of growing too fast has made Tama forget itself. Nyanko-sensei transforms into his majestic form and confronts Tama until Natsume touches its beak and manages to calm it down, freeing Isotsuki.
Tama then sends Natsume and Nyanko-sensei home and they bid their farewell - screencaps - (LHY)
