The characters have very exaggerated personalities, but I do find some of them likable. Ikki and Alice are pretty good characters, I'd say. Admittedly it's hit and miss; Stella and Shizuku are rather annoying. Although the former has decent interactions with Ikki at least. It's probably for the best that this anime focuses on just that relationship and dials the harem aspect back compared to usual.
The most unqualified strength this has is the fight scenes, which are very good. Detailed, well animated and fun to watch. They do a good job showing how the various characters' powers play off each other, and it's nice how Ikki wins his fights by observing and outsmarting his opponents. Sometimes the fight scenes take up entire episodes, and that's honestly when the show is at its best.
But you can't give it too many props for the story and characters. This is a slightly above average execution of a very standard premise. Nothing too much more than that.
