Apparently this series has lots of references. I hate references. Especially the ones I don’t know.

So, finally a proper animation of light novel after the crappy shit by DLE. I didn’t expect there will be references on this series. Including tokusatsu series.

These are the most obvious to me:

Den-O reference. The original line goes like (quoted from Wikipedia)

I am, from start (to finish), at the climax!” (俺は最初から（最後まで）クライマックスだぜ！ Ore wa saisho kara (saigo made) kuraimakkusu da ze!)

Also this:

Just as before, if you watched Den-O you should realize it’s a play from Momotaros’ Hissatsu Waza (part 2). Still from Wikipedia

“My Finishing Attack, Part 2” (俺の必殺技パートＸ Ore no hissatsu waza pāto 2)

And the last one, from Kabuto:

But I guess it works since nobody apart of Kamen Rider fans would understand that.

Most likely there are some others I missed. Feel free pointing them out. Oh, no need to point out obvious Pokemon reference.
