My お気に入り character is Armin. First things first, I appreciate how he isn't the typical "shy" / "insecure" アニメ character who can barely form two words, when asked a question. Armin has had his moments where he was down, but he always comes back around, in the end. Not only is he kindhearted, but also has a very strong heart, and I admire that. I like his bravery, as well, his reliability, and his calculative ability. Overall, I find him to be an amazing character. =)
Hanji is also my most お気に入り character~! <3 I adore her so much. She's so entertaining and funny and I admire her optimism and adorableness and respect and kindness towards everything and she has the most wonderful sense of curiosity and desire to learn and oh my gosh, I just 愛 Hanji <3
Mine happens to be Levi :3 Levi is just an amazing character and his personality might not be to great but deep down he cares about his comrades. Also if the titans ever came to this world I'd rather have Levi on my side rather than Eren. (I still 愛 Eren though ^^;) So in all Levi is the best character in my opinion and I 愛 him to bits and pieces. (And of course あなた cant say no to that cute little face of his. :D)
Mikasa Ackerman because she is awesome. i've never seen any other character like her. and i like it when she's being overprotective to eren. she'll do anything for eren and armin. and because of her past she became stronger and stronger! she's a combination of kuudere, tsundere , and yandere i think. i think she loves eren. :v btw i ship eren x mikasa
