Hi! I've been trying to find this old anime that I used to watch as a kid. It was probably in the early 90s, but in could be from the late 80s.
What I vaguely remember is that, in this anime, the kids would enter what appeared to be some sort of dark room or dark space, and there they would be standing on top of a pentacle (like in the attached picture) and the moves they would do there would be forwarded to some monster or robot, so they would fight other monsters or robots.
I'm not sure if this qualifies as "mecha anime". I don't remember enough to be sure, so perhaps it didn't fit the category after all.
Any hint would be much appreciated. Thanks!

My only thought reading the headline was “why are scientists researching this?” So, of course, the clickbait title got me to read the article.
No frogs, sorry 
In storytelling, even small visual details can become unforgettable. In the globally popular anime "Demon Slayer," one such detail is the short bamboo muzzle worn by a central character. It looks simple and believable, just a piece of green bamboo tied across the mouth. But a new study suggests that this familiar object could not exist in nature as shown in the anime.
To investigate this, Professor Akio Inoue from the Faculty of Agriculture and Agricultural Technology and Innovation Research Institute, Kindai University, Japan, compared anime illustrations showing the bamboo muzzle with the structure of real bamboo. The findings were published in the journal Advances in Bamboo Science.
"I immediately noticed the awkward spacing between the nodes since I have been conducting research on bamboo for nearly 20 years. This intrigued me to conduct natural science analysis of anime bamboo and actual bamboo," says Prof. Inoue.
Bamboo culms are not smooth tubes. They are divided by solid joints called nodes and hollow sections known as internodes. In real bamboo, these sections follow a predictable pattern: the longest ones usually occur near the middle of the culm, while those toward the base and tip are shorter.
This arrangement helps the plant balance strength and flexibility, allowing it to bend without breaking. The anime version appears quite different. The central section looks unusually long, while the neighboring sections seem much shorter than would normally occur.
To test this impression, researchers analyzed 150 anime illustrations in which the muzzle was clearly visible and measured the lengths of its central and adjacent sections. These proportions were then compared with measurements from 112 bamboo samples from two common species in Japan (Phyllostachys spp.). The difference was striking.
In the anime illustrations, the sections next to the longest one were less than half its length. In real bamboo, adjacent sections are typically almost as long as the longest segment. Statistical analyses confirmed that the illustrated pattern falls far outside the range observed in nature.
The study investigated if the muzzle represented a different bamboo species. Historical records showed that only a few species were common in early 20th-century Japan, and their structural patterns were generally similar. None would explain the extreme proportions seen in the anime. Another clue came from the scale.
When compared with average human facial measurements, the muzzle appeared shorter than a real bamboo piece of similar thickness, further suggesting that the design does not reflect the actual plant anatomy.
"This research does not aim to criticize the manga work. Rather, it seeks to contribute to raising public awareness of bamboo and improving scientific literacy," says Prof. Inoue.
Because the analysis relies on simple measurements and basic mathematics, it could also be adapted for classroom activities. Students could study real bamboo culms, observe how their structure changes along the length, and compare those patterns with fictional depictions.
"Our study may raise awareness of bamboo among many people, sparking interest in the relationship between humans and bamboo," says Prof. Inoue.
At its core, the study shows how scientific curiosity often begins with a simple observation, noticing that something does not quite look right. By studying a familiar detail from a popular series, the research turns entertainment into an opportunity to explore plant biology and the mechanics of natural design.
