Favourite Anime of 2012
There wasn't a blockbuster, genre-changing show like Madoka Magica in 2011 (Nisemonogatari sold as much but didn't have the same impact to me) but there were good shows including a couple of surprises and some nice sequels.
- Mouretsu Pirates
Stellvia is easily in my Top 10 all-time favourite anime, and coming from the same team, this didn't disappoint in producing an exciting, 'realistic' sci-fi adventure.
- Girls und Panzer
Not the most original sports anime, but the attention to small details mean that the show's staff clearly did their homework or are total tank otakus.
- Saki Achiga Hen
Less supernatural mahjong than the original Saki, but lots of fun characters and interaction between them makes you want to cheer every single one of them on. They even managed to make Teru more human!
- Kyoukai Senjou no Horizon II
Another sequel, but this one was even crazier than the original in terms of fights both martial and spacecraft. Musashi doing a loop was a sight to behold
- Tari Tari
Music, friendship and PA Works. Felt a bit short, but it featured some of the best supporting cast (especially the parents) in anime
Guilty Pleasure of the Year
High School DxD
Hikasa Youko voicing a sexy redhead = Heaven
Queen's Blade Rebellion
Annelotte was a much more interesting heroine than Reina, and had a nicer harem too
Most Disappointing Show that I completed
Sword Art Online
It wasn't the worst show I finished (Esthetica takes those honours) but from the plot SAO could have been a much better show than it was.
Best Ending
Horizon II
A non-ending ending to lead to Horizon III, but it wrapped things nicely with new couples joining the Musashi. Ok, so I'm a sucker for happy endings
Best OP (Song)
Hyouka - "Yasashisa no Riyuu" by Choucho
Been a good year for Choucho, singing the OP to hit series Hyouka and Girls und Panzer.
Honorable mention :
Nisemonogatari - "Platinum Disco" by Iguchi Yuka
Saki Achiga Hen - "Miracle Rush" by StylipS
Best OP (Animation)
Nisemonogatari - "Platinum Disco" by Iguchi Yuka
There's something hypnotic about Tsukihi's hand movements and her dancing... (puts the video in loop)
Best ED (Song)
Tari Tari - "Shiokaze no Harmony" by Shirohamazaka High Choir and Sometimes Badminton Club
Honorable mention :
Joshiraku - "Nippon Egao Hyakkei" by Momokurotei Ichimon
Best ED (Animation)
Joshiraku - Chibi dancing ftw!
Honorable mention :
K - Naked Neko, all you need to know
Best Insert Song
Tari Tari - "Kokoro no Senritsu"
Beautiful song. I think I like the duet version better than the choir version.
Song that deserved a better show
Aquarion Evol ED - "Gekkou Symphonia" by AKINO and AIKI from bless4
Could have said the same with the original Aquarion's OP :D
Honorable Mention :
Sword Art Online ED2 - "Overfly" by Haruna Runa
Best OST (Vocal)
Tari Tari
A show about a choir club would have lots of songs and most of them were great. I even like the school song and Amigo! Amigo!
Best OST (Instrumental)
Girls und Panzer
In addition to its details to tanks and tactics, Girls und Panzer also featured authentic military tunes for each of the teams. Ok, so it's easy to pick "Battle Hymn of the Republic" to represent Saunders, but Hamaguchi Shiro (who also did the Tari Tari OST) still had to arrange it with modern musical instruments. There is also the vocal version of Katyusha which is helped by the fact that Uesaka Sumire speaks Russian
To top it off, the original compositions are fantastic too. The Ooarai Senshado theme that appears in multiple forms throughout the show is one of my favourite pieces of instrumental music.
Best Eyecatch
Sengoku Collection
Lots of eye candy :D
Most Shocking Scene aka "Did they really do THAT?"
Girls und Panzer Ep 1 when the camera moves back and we see where the school and town is located
Even after watching anime for over 20 years, that still managed to raise my eyebrows a little
Best Fight Sequence
Futayo vs Gin - Horizon II ep 12
Could have also picked other duels from the show like Neito vs Walsingham
Honorable mention :
Kiritsugu vs Kayneth - Fate/Zero ep 8
Favourite Male Character
Otonashi Io - Acchi Kocchi
Nosebleed inducer extraordinaire!
Honorable mention :
Crossunite Tenzou - Horizon II
Favourite Female Character
Katou Marika - Mouretsu Pirates
Honorable mention :
Watashi - Jinrui wa Suitai Shimashita
Nakahara Mai at her snarkiest best
Favourite Hetero Couple
Io Otonashi and Tsumiki Miniwa - Acchi Kocchi
Honorable mention :
Tenzou Crossunite and Mary - Horizon II
Favourite Yuri Couple
Jenny Dolittle and Lynn Lambretta - Mouretsu Pirates
Honorable mention :
Margot and Malga - Horizon II
Toki and Ryuuka - Saki Achiga Hen
Favourite Supporting Character
Fairies - Jinrui wa Suitai Shimashita
Hilariously morbid at times while keeping their happy grins.
Honorable mention :
Tachibana Gin - Horizon II
Almost every non-major character in Saki Achiga-hen
Favourite Character Quirk
Hanada Kirame's Subara! - Saki Achiga-hen
For a minor character, Kirame's Subara and super-optimism was a joy to watch when facing the monster Teru. And the back-story where she finds out she was meant to be a sacrifice and perfectly OK with it was touching
Most Impressive New Seiyuu
Komatsu Mikako - Katou Marika (Mouretsu Pirates), Wagahai-san (K)
