eww, got further in this episode, found another thing they fucked up. The original Komugi had an idol friend/rival who turned into an
evil magical girl, and was secretly behind the monsters. but in the new version she turns into a
good magical girl and her and Komugi team up to fight the monsters. That's just lame, the old way at least has comedic value.
(Also amusingly, Nichijou is classed as Shonen.)
That's because strictly speaking "shonen" means "boy" not "battle". As it, it was published in a boy's magazine. The Japanese classes all manga series by target demographic of the magazine it was in. the four core demographics are shonen, seinen, shoujo, josei. The
style is irrelevant, everything is packed into one of those four boxes based on who published the manga.
For example, just take a look through the "seinen" stuff:
http://myanimelist.net/anime/genre/42Non Non Biyori, Chobits, Golden Time, My Little Sister ..., Hanasaku Iroha, Acchi Kocchi, Non Non Biyori, Oh My Goddess
And Shonen stuff:
http://myanimelist.net/anime/genre/27Nisekoi, Rosario to Vampire, Your Lie in April,
Gekkan Shoujo Nozaki-kun, Inu x Boku SS, Love Hina
Yeah, get that:
One Punch Man and
Gekkan Shoujo Nozaki-kun are both considered shonen series.
"Love Hina" is shonen (boys) whereas "Oh My Goddess" is seinen (mens), even though Love Hina has way more boobage.
