>>1473407Start tokusatsu with Kamen Rider 555, this season in particular is a bit controversial because of misunderstandings but it makes up for it by having cool designs, a charismatic cast and a "lost" main character trying to find his place in the world, which fits the vibe you described in OP.
If you feel like taking a break from 555 then try Kamen Rider W, it's a detective-themed season mixing action and mysteries, it has two main characters but they "fuse" to become one Rider, it's more straightforward but addicting to watch.
It might seem like going from Doremi to Kamen Rider is a big jump in genre but not quite, both are shows made by Toei, and 555 was even made around a similar period to Doremi (early 2000s), in fact both shows aired side to side and KR Agito even has an episode with Doremi plushies as a reference.
