Something modern and with supernatural elements, hence my story. Probably got influenced by Bleach because it was my starter anime. As in the first one that I actively followed then proceeded to the manga (followed it till the end too). When I was young, I liked Yuyu Hakusho and Shaman King, too. And even in works that do not have that as a primary genre that I watched as a kid, like say, the first Digimon, my favorite parts were the arcs that took place in the real world. Maybe it's the interest in how people and technology interact with the more "spiritual" elements of life and the magic.
Eventually, the harem elements started creeping in when it comes to my own preference, largely thanks to the Toaru series and Shakugan no Shana. Then followed by Date a Live, Mahouka, Black Bullet (this is moreso sci-fi dystopian than supernatural tho but the vibes are still there), and Strike the Blood. What grips me to like the female ensemble, I feel, is not the whole "I am in a relationship with everyone" part but how a male protag fights and develops bonds with badass and pretty/cute girls with their powers (as well as the token muggle or two). Plus the merch, so there's an element of consumerism and sex appeal for me.
Persona, Princess Connect, and Trails of Cold Steel then solidified such preference further.
Ideal story is what I'm writing ? but it's very heavily inspired by the mentioned shows and games anyway, so those stuff I mentioned count.
