Bleach, Kekkaishi Recommendations
Well...Kekkaishi isnt about shinigami and swordfighting but the manga has the same feel to it...a boy in black Bleach-like clothing fights against weird monsters...(like the main protagonist in Bleach)...he gets stronger and stronger, tries to defend THE GIRL who also happens to be very similar to the main female character in Bleach.
There is a secret society (very soul societys like)...and there is the evil group...
Sooo...all in all...very similar yet different.
P.s. Kekkaishi is in my opinion the tame version of Bleach.
Imagine Bleach never had the Karakura Town kids go to Soul Society and instead Ichigo fought hollows. You might have something like Kekkaishi, a series that has the same feel of the early chapters of Bleach. Kekkaishi is surprisingly deep for a shōnen manga (something Bleach goes in and out of) and focuses on it's protagonist much more than Bleach does.
