Voiced by Emiri Kato
The bright red one-piece swimsuit is striking, but even more so, the double bun hairstyle seen only here is great as well.
She is a second year student at Ryouou high school. She is in a separate class from Konata and the others, but they visit each other during break times. Though she is the tsukkomi that has to deal with Konata’s otaku remarks, when she is teased by Konata, she starts blushing like a stereotypical tsundere. As a responsible person, when she is together with Konata, Tsukasa, and Miyuki, she inevitably becomes the mediator.
Swimsuit
A Tsukkomi Tsundere Girl
While she’s not particularly gaining any weight, she always keeps an eye on it. She has created a senryu(?) that goes “It’s my weight again! I gained it all back in, like, the blink of an eye!”
Hiiragi Kagami
While they don’t reach Miyuki’s level, Her grades are excellent. Her summer homework takes top priority, and she completes it before anything else. She is diligent and always puts in serious effort.
Kagami and light novels
Even though she generally doesn’t enjoy things like anime and manga, she loves light novels, like Konata. Among the one’s she’s read, it seems she especially likes “Full Metal Panic!” She even has a stuffed animal of Bonta-kun from the series in her room.
She likes wearing high socks that reach up to her knees. And if we're going that far, I’d also like to see her wear thigh high socks that show off some zettai ryouiki.
Hiiragi Kagami
Kagami’s facial expressions
Her distinctive tsurime makes her appear to have a tough personality. She’s not “vicious” like Konata may say, and is actually a good-hearted person deep down.
Her hairstyle is twintails tied on both sides. For the brief moment where she had a ponytail, it suited her quite well.
