^ If you like Slice of life like Honey and clover I recommend
Bokura ga Ita ---> Love in a school (its so hard to summarize Slice of life anime x)
My favorite Slice of life/romance/comedy anime of all time though is
Kare Kano (His and Her circumstances)
Its about a girl who thought she was perfect all her life, who runs into a guy that may be even more perfect than she is. She starts to realize that she's being lieing her whole life and doesn't even know herself... that she was just living so she could be praised. She falls in love and tries to discover her true self.
+ Very Funny xD
+ The love story is cute... but still realistic
- The animation budget drops towards then endxD
- The anime was never completed so you need to read the manga to see the end (Which is amazing so I highly suggest you do)
If you like Yamato Nadeshiko Shichi Henge I suggest:
Ouran High School Host Club:
A poor girl gets into a private rich high school through a scholarship. She doesn't care alot about her looks so she looks like a guy. She is looking for a quiet place to study and stumbles into the "host club"~ a club of Hot guys who want to entertain girls... she accidently breaks a very expensive vase... and she is blackmailed into entering the host club (as a male) to pay off the debt.
+ Funniest Reverse Harem I've ever seen
+ Awesome Characters (omg Tamaki<3)
- Anime not completed... you need to read the manga
For Slice of life I also reccomend you watch:
Fruits Basket
Lovely Complex
Toradora!
Nodame Cantabille
Itazura na Kiss
Skip Beat
School Rumble
Saiunkoku Monogatari (Reverse Harem)
Ranma 1/2
For anime Similar to XXXHolic I reccomend:
Mushishi:
In older Japan a man with the power to see the "mushishi" (weird ghostly/bug things) travels and collects stories and rare items. Basically each story starts with someone with a problem and he fixes it... is very similar to xxxholic <3
+ Very creative stories
+ Very nice animation
+/- Mellow... can be a good or bad thing... will put you to sleep maybexD
I also reccomend Pet shop of horrors... although it is very short
Its about a chinese man who owns a petshop. The pets he gives away are mythological creatures~ and people come to him to have the pets solve their problems (For example if a child dies they buy a pet to replace them). When they but the pet~ they must make a contract~ if they break this contract... very bad things will happen to them. The shop and owner remind me ALOT of Yuuko xD
+ Creative interesting Horror Plot
- Only 4 episodes
Anime Similar to Basilisk:
Rurouni Kenshin (described in my first post)~ Specifically "Samurai X" Ova's... which have a very similar aura to Basilisk.
I also Highly Recommend Berserk =3
About a man with a Huge sword... but a miserable past (Born from the corpse of his mother who was hung from a tree... then his foster mom contracts the plague... and his foster dad sells him into prostitution and tries to kill him) ANYWAYS~ He joins an army trying to save this medieval world and make a new order... Lots of fighting and action Plus a philosophical story... one of my favorite anime.
+ Good Action
+ Good Characters
+ Pretty Deep
- Not completed... you have to read the manga (which after THAT ending you'll want to xD)

Hope that is enough lol
