What should i watch next?

hola there anime fan, after checking out your "plan to watch" list, I have some to reccomend.

1. Since tu like stuff like clannad and ángel beats, I suggest watching Air siguiente kind of the same. Sola was also a good anime although somewhat hard to understand, no cruzar, cruz that incredibly hard to understand because of the insane plot twist at the end but none the less a good anime.
2. Out of the blue, I recommend watching special A, its hilarious, romantish, and that art is that of SAO o better.
3. Elfen lied was the first anime that made me teary eyed due to the emotional stress in it. Although it made me almost cry, others usually don't. It's a good watch but be warned there's a bit of gore and mature themes.
4.Btooom would be a good watch but its only 12 episodes which made me angry considering How farther along the manga is but still enjoyable with a good ending.
5. Shakugn no shana is also quite enjoyable, just another good anime although shana's somewhat taundere

Bleach, Naruto, One Piece

best 3 animes ever.............u will luv it for sure...........

Tonari no kaibitsu (Romance, kinda school)

K-On (Kinda cute and funny, más girls enjoy this anime)

Diabolik enamorados (Hot vamp guys and a human girl)

Brothers Conflict (Hot guys and a girl)

hetalia (Countries put into human characters, funny)

Maid Sama (Romance comedy)

Fullmetal alchemist and Fullmetal alchemist brotherhood (Alchemy, some action)

Soul Eater (basically the name, action)

Theres also the popular ones like Death Note, one piece, naruto ect but tu probably already know about them all.

If tu want más tu can ask and I apologize if I have accidentally used some tu have already watched :)

From your lista I see that tu like a lot of supernatural and sort of darker anime. For that I suggest:
+Ghost Hunt
+Psychic Detective Yakumo
+Zombie Loan


But tu have also watched upbeat animes like Shugo Chara and action like Code Geass, so animes that are like these and supernatural:
+Natsume Yuujinchou
+Blue Exorcist (listed on your to watch)
+K-project
+07 Ghost


[pictured is Ghost Hunt. I actually just finished watching the series today and I loved it. It had a good amount of scary scenes and suspenseful episodes. But it was also humorous and had some of the best characters I've ever seen in an anime]

Hm...well I see tu like Code Geass so I recommend Death Note for that. And tu like Another and Higurashi so another psychological anime anime tu might like is Monster. And you're planning to watch Hotarubi no Mori e, so if tu end up liking that then I recommend Natsume Yuujinchou which is really similar, and an amazing series.
I'm bad at recommendations but I hope I helped =)
