My fav manga of all time:
http://www.mangago.me/read-manga/prince_of_tennis/
Other sport shounen cas im totally into that:
http://www.mangago.me/read-manga/haikyuu/
http://www.mangago.me/read-manga/eyeshield_21/
http://www.mangago.me/read-manga/kuroko_no_basuke/
Because it's a hell of a trip and even confusing at times:
http://www.mangago.me/read-manga/tsubasa_reservoir_chronicle/
Because myths and spirits and stuff:
http://www.mangago.me/read-manga/xxxholic/
Because it's damn funny specially if you're familiar with a lot of manga(has a lot of references to other manga):
http://www.mangago.me/read-manga/sket_dance/

Oh I forgot something. I recommend these two if you really like real good heavy plots. They're super interesting and u never know what's coming next.
http://www.mangago.me/read-manga/basara/
http://www.mangago.me/read-manga/7_seeds/
Yay!! (๑❛ᴗ❛๑) Hope you like at least one of them!!!!
Also since you like Basara and 7 Seeds, maybe you'll like:
http://www.mangago.me/read-manga/doubutsu_no_kuni/
http://www.mangago.me/read-manga/immortal_rain/
I didn't recommend them before cas ik not everyone likes things that have heavy plots but I think you might like em.
Can someone recommend a long but really entertaining manga series? Its doesn't have to be complete or anything, but an example would be like Magi or Enen no Shouboutai (Fire Force) or umm Nanatsu No Taizai (The Seven Deadly Sins)
I've read all those though...... ╥﹏╥
Thanks in advance!!! ヾ(☆▽☆)
