Sazer-Pisces

Ai Uozumi (魚住 愛Uozumi Ai? ) is a caring and friendly nurse working at the same hospital as Akira. Right after their first encounter, Ai developed a crush on him. Ai was in love with Akira Dentsuin. Later that day, she and her long-time friend Tappei were attacked by Lucia, and Ai had to transform to protect herself. Just in time, she was saved by Sazer Remls (Akira Dentsuin). Eventually she found out that a man she had known for years was in fact related to her, and this man was kidnapped by Logia. She followed them and freed him in time. Ai has a more than kind nature, even feeling mercy for those who tried to kidnap and kill her; but she is also serious and devoted to her mission. She is the youngest Gransazer.

With her Knuckle Riser, Ai transforms into Sazer-Pisces (セイザーパイシーズ Seizā Paishīzu? ), the water warrior under the sign of Pisces, whose armour is shaped after an orca/ whale in aqua. Sazer-Pisces' main weapon is the Aqua Blitz, a small gun. Its finishing attack is called "Blink Shot", which is a strong blast.
