It's been a while since I did this and not much has really changed but I wanted to post an update anyway.
I figured since I haven't really added any new manga to my roster I'll give a brief description of where everything is.
Naruto - We're in the middle of a ninja war. While everyone else is on the battlefield, Sasuke is getting the dirt on what really went down in Village Hidden In The Leaves. He's decided to join the fight against Madara.
Bleach - Currently we're in an arc going over the history of Ichigo's parents.
Beelzebub - The gang's back at their old high school, but what's up with all these demon contractors?
The World God Only Knows - Keima's gone back in time (actually his spirit switched places with his younger self) on a mission to fix the present.
History's Strongest Disciple Kenichi - The gang is in the middle of an all out assault by Yomi while they were enjoying a day at the water park. Surprise, surprise: Odin..er Ryuto teams up with Kenichi to battle Kensei.
Ratman - Been on hiatus for a while now and I'm hoping it hasn't been dropped. We were in the middle of the Iska arc.
Cage of Eden - The series concluded with what I think was a rushed ending. Turns out everyone was in the future. The island wasn't on the map because it was man-made about 200 years prior as memorial/potential landing spot for them. Roughly a couple years after making this final discovery the gang has crafted a boat capable of getting them off the island and back to Japan. They are apprehensive though because no one has come to the island at all in that time and they wonder if there is really a civilization left to get back to.
Fairy Tail - Fairy Tail wins the game! But what's all this about dragons coming to kill everyone and opening a magic gate?
Noblesse - This series could possible be concluding soon. Master Rai is using what may be the last of his power against 3 three union members gone wild. He's won the fight, put at what price?
Bartender - The stories are too random to really break it down. There is an ongoing (but rarely utilized) arc where the hotel manager and Ryu are having a kind of father/son relationship and his granddaughter has a thing for Ryu.
The Breaker: New Waves - After watching Shioon being manhandled for most of the series it's kind of good that his ki center has (kinda, sorta) healed and he's kicking all kinds of ass. But where is he and why are these people trying to take him captive?
Hajime no Ippo - Vorg has taken the US Championship! So when's Ippo gonna fight again?
Hunter X Hunter - So far the series is on (ANOTHER) hiatus with the ending of the last arc showing Gon finally meeting his dad at the top of the World Tree. Besides that there's a Kuparika flashback arc but the main story is on hiatus.
Mangaka-san to Asistant-san to - Another series that's way to random to describe. Still incredibly funny for 8 page stories.
Karate Shoukushi Konihata Minoru - It's been a full year since both Minoru and Mutou lost the karate championships. Minoru and the gang (minus Mutou who's gone abroad to study) are currently in the middle of a mixed martial arts battle.
Medaka Box - Another series that appears to be closing soon. Medaka has decided to leave the academy and fulfill here familial duties. In what appears to be the final arc, Zenkichi has arranged for her to contest with everyone at the academy before she leaves.
Toriko - The Bishokukai is raiding the Cooking Festival and their targets are apparently all the world class chefs.
Freezing - Currently on hiatus (happens a lot, I know), the new arc follows the introduction of Team 13 Valkyries.
Sekirei - Also looks like it's close to the end. The final "game" in the Sekirei Plan has started.
Gamble Fish - After a long hiatus only 2 issues has come out. Tomu bets his life for 30 million yen. We're pretty sure he's going to make it.
Liar Game - Akiyama wins Bid Poker and Team Harimoto is withdrawing from the game completely. But Yokoya is still out there and he's cleaning up.
Zen Martial Arts Academy - Alas this series was cancelled. It was fun while it lasted.
The God of High School - Remember that world security plot that showed up in the first issue and we never saw again. Well it's back. What's the deal with The Key?
My Little Sister Can't Be This Cute - On hiatus for a looooong time. It might have been dropped.
Simon Sues - ditto
Girls of the Wild's - It's Dal Dal vs. Lee Moon Young! Song didn't know it but he was coaching them to fight each other.
I'm going to stop there. I haven't really been keeping up with Gintama or Conan as I said I would. Maybe some other time.
