While saving a child from harm, otaku Asahi Ikusaba is transported to another world and believes he has reincarnated with cheat skills similar to those of the characters from his favorite games and novels. Unfortunately, reality strikes when an encounter with a powerful monster shows that he is still nothing more than an average person.

In this moment of extreme danger, Asahi instinctively calls out to his overly doting sister, Maya, who appears out of nowhere, possessing the overpowered abilities he thought he had. Maya is ecstatic to see her brother again and resolves to use her newfound powers to protect Asahi no matter what.

Together, the close-knit siblings attempt to find a way back home while enjoying their new lives. However, it soon becomes clear that their arrival in this world may have had a purpose. With the Demon King's overwhelmingly powerful army approaching, no one but Maya seems to be able to stand in its way.

It's better than you thought

At first I also expect the most generic isekai plot with the over protective sister type from the name and sypnosis. But while yea most of it is still the generic plot, it's better and more wholesome than expected

First of all the isekai gimmick of course is unique, but unlike most other unique gimmick, this one does live up the gimmick and follow through and make the gimmick actually useful to the story.

Now for the sister part, it's still a bit weird and play in to the "weird" stuff, but there are still some moment that's very wholesome too.

The quality thought ...

Mixed Feelings
Anyone ever watch a show specifically for one character? Everyone has their own reason for watching something, no matter how odd or specific, no matter how the thing they decide to watch looks like it’ll turn out. Sometimes they just like the vibe and wanna experience that all the way. Sometimes they just really like a song or one of their favorite artists is doing the OP or ED. Sometimes clips have convinced you that a show has baller fights, or in the case of this show, clips have demonstrated one character who sells the anime alone.

It’s not the sister. In fact, let’s get this ...

Art: 5
Animation: 3
Music (Background Tracks): 4
Plot: 2

Characters and backgrounds were given a surprising amount of detail to their designs.

The animation felt stiff and lacked motion.

None of the music tracks used in the show were particularly impressive nor offensive. Maya's theme sounds more like a rift of a few notes than an actual track.
