This is Hidan no Aria AA's spin-off manga adaptation with completely new female lead and new characters. If you enjoyed and are a great fan of the original Aria of the Scarlet Ammo anime you would definitely enjoy this because it's made for you. Even though it's a spin-off with new, unknown characters it managed to entice me. Old jokes are recycled including all those sundries that made the first season amusing to watch (Bulletproof uniforms, parachutes out of nowhere, Reki's monologue). Old characters make cameo appearance and act as comic reliefs (I had a blast with Kinji's recurring appearance and his exchanges with the new lead). Aria takes the spotlight as usual and there's a visible character development in the new girl by the end. Story is episodic slice of life/action with yuri/fanservice undertones. The backgrounds look detailed, the characters well animated for a spin-off and they sound moe. The opening and ending sequences are simply amazing. Basically, I think this is what a good spin-off should look like and function: amusing, action-packed but funny and light and not-plot-less.
