The harem genre often goes hand in hand with ecchi and, based on how strong the latter is, the audience attracted can differ drastically. Aesthetica of a Rogue Hero clearly fell under the harem and ecchi category in its time, found its crowd, and almost 10 years later, is there a possibility for Aesthetica of a Rogue Hero Season 2?
What happened so far in Aesthetica of a Rogue Hero

In den letzten 30 Jahren wurden Menschen durch zufällig auftauchende Portale weltweit in Fantasiewelten entführt. Tausende von Menschen verschwinden, und nur die Hälfte von ihnen kehrt sicher nach Hause zurück. Sie kehren jedoch verändert zurück, da sie nun mächtige körperliche Fähigkeiten und manchmal auch Magie einsetzen können. Sie werden dann von Babel, einer mächtigen Organisation, die von den Vereinten Nationen unterstützt wird, aufgenommen und in Spezialschulen eingeschrieben, wo sie lernen, ihre Kräfte besser zu nutzen. Das wird ihnen gesagt, doch das eigentliche Ziel ist es, sie so auszubilden, dass sie später auf die Schlachtfelder geschickt werden können.
Akatsuki Ousawa hat gerade den Dämonenkönig der Welt besiegt, in die er transportiert wurde. Obwohl die Einheimischen verlangen, dass er bleibt, nachdem er sie von dem Drachen befreit hat, will Akatsuki nach Hause zurückkehren. Es stellt sich heraus, dass er Miu, die Tochter des Dämonenkönigs, entführt hat, um ein Versprechen einzulösen, das er seinem Todfeind gegeben hatte. Sie sind beide in Babel eingeschrieben, wobei Miu als Akatsukis amnesische Schwester durchgeht. Der junge Mann wird schnell als einer der mächtigsten (wenn nicht der mächtigste) Menschen auf dem Campus anerkannt. Eine Tatsache, die er sehr gut kennt, spiegelt sich in seinem Verhalten wider: Akatsuki ist arrogant, voller Selbstvertrauen und in den meisten Situationen ziemlich entspannt. Er ist auch ein sehr aktiver Perverser, der dank seiner Macht nicht davor zurückschreckt, junge Frauen zu befummeln und ihre Unterwäsche zu stehlen. Seine Mätzchen ziehen die Aufmerksamkeit verschiedener Parteien mit unterschiedlichen Motiven auf sich, während dunkle Machenschaften und Unruhen im Zusammenhang mit Mius Verschwinden in der anderen Welt aufkommen.
What is going on with Arms?

Aesthetica of a Rogue Hero premiered on July 6 and ended on September 21, 2012. It is directed by Rion Kujou, written by Ryunosuke Kingetsu, with the score composed by Kayo Konishi and Yukio Kondo. It ran for 12 episodes.
Let us get something out of the way right now: Aesthetica of a Rogue Hero is not made for everyone, not even the casual anime watcher. Its fanservice and ecchi are extremely strong, and what should be a nice story is relegated in the back. What could have been done with Akatsuki is wasted on bad comedy and high hormone levels?
The protagonist is a bit of an oddball in the genre: harem anime usually uses an average-looking hero weak in the face of the female attributes, fainting at the sight of cleavage, sobbing in apologies when entering the wrong room (the one full of naked ladies)…Here, we are confronted with a perfect “Gary Stu” in all his splendor. Akatsuki is overpowered, overly confident, smart, good-looking, and extremely comfortable with women’s bodies. He is also comfortable with not respecting their private space. When female characters do not end up naked or in compromising positions thanks to that ecchi magic, you can be sure that Akatsuki will initiate the fan service. However, the scenario wants the viewers to understand that he is loyal and noble in his intentions, and therefore, his acts are to be considered good deeds. The mental gymnastics you have to go through to justify him fondling Miu’s breasts to teach her how to wear a bra, forcibly removing the underwear of female attackers as he does not want to fight women or forcing two girls to pee to accompany a third one who cannot hold herself anymore, will take you straight to the next Olympic Games. It isn’t easy to perceive it as gallantry, even more so when it is clear that he takes pleasure in his acts.
The rest of the main cast is composed of his harem, and all you will find are the usual stereotypes. Their personality is predictable, and they are here to tick a specific box. To understand exactly how much space the overused ecchi trope is taking, picture Fire Force with Tamaki as the only character we have to follow and how things would unfold then. And that is a shame considering the interesting characters Aesthetica of a Rogue Hero keeps hidden: Kaido and his terrorist group, Hikami being part of an underground organization, or the people behind the political turmoil in the fantasy world. Some solace could have also been found in showing in more detail (and better writing) how Miu is trying to adapt and fit in. The premises of the story are ignored. Even as we sometimes feel that a blurry and vague scenario is somewhere somehow, the plot gets no development until the last 2 episodes, where they all fight some enemies, and the stakes start getting higher. Aesthetica of a Rogue Hero has no visible plot, no tension, and conflicts are glossed over. The animation is average but limited. That can be clearly seen during fight scenes where visual shortcuts are taken. The experience of the studio in hentai and ecchi productions shine brightly with this title, where scenes with sexual tones are more polished than the ones actually needing fluidity.
Arms went bankrupt and closed on August 4, 2020.

What are fans saying about Aesthetica of a Rogue Hero Season 2?

The community is small. Aesthetica of a Rogue Hero, a pretty niche anime in a category where similar products are abundant and with only 12 episodes, did not really have the strength to stand higher than its fellow ecchi shows. It does not have a subreddit and is not discussed on Twitter. The term does appear in several posts, but never as part of a real conversation.
The anime received a mediocre score on MAL and a surprisingly good one on IMDB. But then you take a look at the comments for the latter, and you understand the type of crowd an anime like Aesthetica of a Rogue Hero pulls in. Season 2 does not seem to be something both parties envision nonetheless.
