Mato Seihei no Slave

 A fantasy series with an ecchi touch, count me intrested!

And so we started watching this Winter 2024 season anime, in the hopes for some decent story apart from potential fan service galore!

Yuuki finds himself suddenly trapped in the Mato dimension, a place where men fell to the bottom of society.  About to die, he is saved by a girl called Kyouka, a member of the Seventh Unit of the Anti-Demon Corps.   But she has a strange power, and in order to have it manifest to the fullest, Yuuki has to become her personal slave...

He agrees to this, becoming a big beast after he licks her fingers, quickly dispatching of the enemies, only to transform back to his own form after the battle.  Her powers do force her to reward her slave every time he does a task, her body losing control as she has to hand out the rewards.  He becomes the girls dorm everyday housekeeper, while being the slave to Kyouka when combat arises.

He settles in in the dorm house, getting to know the girls a bit better and their personalities.  He learns what drives them and why they became demon hunters, as well as what their peculiar quirks are, including being severly beaten in "strip Streetfighter". 

Yuuki learns that Kyouka hunts a Unihorn, a monster that killed her parents.  Tracking it down, it is oddly ridden by a humanoid itself, which Yuuki seems to feel is her missing big sister.  On a mission with another one of the girls, Himari, in a duel against her older sister, he learns more about his corps companions.  He decides to help Himari to overcome her sister, showing he can devote himself to multiple mistresses in the team if he puts his mind to it.  Himari figures out the technique how her sister fights, but she holds one more card with her ultimate technique.  But together with Yuuki she gets back up and breaks through the technique with a daring move, clinching the victory.

As the duel continues, Shushu faces sahara, a sleepy girl from the other squadron.  Both boosting physical powers, it quickly becomes a slugfest.  But when Sahara unleashes her full power from the brink of defeat, she defeats Shushu, and seriously denting her confidence.  Yuuki gets to check on her, being kissed by the topless girl, as she actually developped a crush on him.  But the duel is interrupted as the Shuuki launch an attack, breaking the protective barrier.  Both squadron's team up, combining their powers to oppose the threat.  

Managing to hold them back, he gets a reward of two girls, before they go visit the 6th squadron's dormitory.  As he helps there as caretaker, Shushu keeps pondering on him and their kiss.  He learns at the dormitory that Himari's elder sister is really fond of her little sister, her room covered in pictures of her.  The 6th squadron commander declares she wants Yuuki as a commodity for her own team, going as far as trying to seduce him, but he is saved by Shushu as she barges into his room.

As the squad prepares to battle the humanoid Shuuki, they all get to see their effects on Yuuki, like when Nei uses him he becomes a fast scouting form... with X-ray vision showing through the other girls clothes.  While when Shushu mounts him, he becomes a true brawler, but not insanely powerful meaning her ability won't be used in combination with Yuuki to her distress.  As he escorts Nei to school, he learns she joined the force to find her missing parents again.

 

The battle begins against the Shuuki, as they take Yuuki along with them, snatching him from Kyouka in the fight.   He finds himself surrounded by three girls, including one that is indeed his missing bigger sister Aoba.  Together with Coco and Yuno she runs a hidden village of people that still have human souls inside their Shuuki bodies.  She explains the reasons of why they have enimity towards the Demon Defence Force to Yuuki.  She tells him what happened and how she became in the form she is now, being used as a lab rat with the promise of a cure.  

In the meantime, the two Defence Force squadrons mount a rescue, being opposed by Coco, and being faced by Shushu and Sahara.  The sisters face Yuno, as both commanders move on to free Yuuki.  As Kyouka and Aoba engage in a discussion with Yuuki about their viewpoints, they realise peace is not an option and Aoba binds Yuuki to keep him out of the fight.  Tenka faces Aoba, as battle commences.  But as the girls find themselves in a tough fight, the Shuuki upper echelon prepares to make their appearances on the battlefield.

 

The girls battle with all they got, some managing to overpower their opponents, while others have a tougher time.   As the big three arrive, the commander and Yuuki manage to ward off danger for now.  Allowing Yukki's sister to leave with her people, they decide to go look further into the stories of the genetic manipulations.

So, this was an okay if not great show, and I will probably watch season 2 when it comes out, if only for Shushu and her assets.  But to say it was awesome is pushing it for me...
