Despite of the graphic and the animation and how they animated this series. This anime story really really unique, it's better than other Isekai with a revenge flavor. That the mc are naive just to kill one person and be nice at her word, this anime MC are different. If he want to kill, he will do it. A loot of person here maybe not recommended it just because how they animate it with 2D and 3D combine. But for me I do really really enjoy it. So you will enjoy it too if you looking for a story where the MC took a revenge. hopethis got 2nd season. With this animated are fine for me. No need for upgrading it.
