Suggested Manga

Franken Fran is excellent stuff, except it's a pity the translators (SnoopyCool) only did 23 chapters and left it on a major hiatus and will snap at anyone else who tries to pick up this series to translate.

Also, Onani Master Kurosawa [Fap Master Kurosawa] is excellent stuff. It's very short at a mere 30 or so chapters, and a bonus chapter.

You seemed to like Love Hina. Try Akamatsu's ongoing series, Mahou Sensei Negima. It starts as the love child of Harry Potter and Love Hina, but it turns into an action shonen later on and keeps some of the ecchi elements.

Franken Fran - Read the first chapter, looks good, and it's pretty funny too. Ongoing + haitus though
I don't know how to do a strikethrough of what I wrote. I'm probably going to end up reading this one. Thanks.
Onani Master Kurosawa - I think I accidentally came across this one before, but it seemed sort of weird so I never read it. I'll give it a go.
Mahou Sensei Negima - I don't remember where I am, but it was definitely past volume 15 or so.

-Cat Street. HOHO
-The Deep Love series, starting with Ayu no Monogatari (is saddening).
-Wolf Guy--Ookami no Monshou. Need no words here.
-Vinland Saga. Yes.

Cat Street - seems interesting.
The Deep Love series, starting with Ayu no Monogatari - I can do sad. How long is the series?
Wolf Guy - I'm not sure if this one's done or not. It's 2 volumes right? Certain sites have it at 4 and ongoing.
Vinland Saga - Took a look at the first chapter. Strangely reminded me of Berserk. It was really good though. But it's ongoing

I agree with DNA2. It's a great manga, contrary to its completely piece of pomegranate anime adaptation. Just play one episode with the English voice actors, and you will understand why they should have kept it as a manga.

Also, try Higurashi No Naku Koro Ni, if you're into that sort of mindscrewy type of manga.

Higurashi No Naku Koro Ni - I remember reading this from Newtype a long time back. It's almost done scanlating, so yeah.

Watashi ni xx Shinasai! isn't a finished series, it's fairly new, but it's great. Give it a try, bro.

Not to say it's not, but I hate waiting. If I get into a really good series, I'll be disappointed if I'm only able to read 1 chapter at a time every couple weeks.

I also want to mention Half & Half. It is only a one-shot but is was a really enjoyable read. In fact, I think Joe was the one who recommended it to me.

This. Read Half & Half. If you don't mind on-going series, Kimi no Iru Machi by the same mangaka, Seo Kouji (Suzuka), is pretty good, and just got to a very dramatic cliffhanger on its last chapter (70something).

Fap Master Kurosawa is one of my all time favourites. Re-read it two days ago actually. Shi't was to cash.

Mahou Sensei Negima is a must for Akamatsu fans.

Kano Yasuhiro (Pretty Face) does some great work. Mx0 is a pretty fun ride while it lasted (~100 chapters). Wish it didn't get cancelled. Snow in the Dark is a great read, give that a try.

Re-Take Obligatory Re-Take recommendation, especially if you're an NGE fan. (Unless you're opposed to sex, though there is an All-Ages version, which I don't believe has been scanlated though <_<)

Half & Half - just read it this morning. I gotta admit I really liked it. It was sorta sad and happy at the same time lol. But yeah, thanks.
Mx0 - I've read this one before. I agree, it was really good, shame he had to end it so quickly though.
Kimi no Iru Machi- I actually looked into this right after finishing Suzuka. I sort of want to read it after reading ch1, but I would hate to read it 1 chapter at a time. Well it sort of worked in Suzuka, like how each chapter was began and ended within itself( most of the time). If it's like that, I wouldn't mind keeping up with it.
Snow in the Dark - same author as Pretty Face, and a 1 shot too. I'll read it.
Re-Take - people have said it's like the sequel to NGE. I thought NGE wasn't finished yet? I've read up to either volume 9 or 10, I forgot. As for the sex thing, I'd rather read the original than all ages version.
