Endou Natsumi (円堂 夏未) (formerly Raimon Natsumi (雷門夏未)) was the third manager for the Raimon soccer club. She is also the daughter of the chairman Raimon Souichirou of Raimon Junior High. In Inazuma Eleven GO , she is married to Endou Mamoru.
[Edit]She has long and wavy auburn hair that got longer after the FFI arc time skip and eyes of the same color. She has long bangs which are parted in the middle and pulled in the back. She is always seen in a Raimon female uniform but slightly different from those which Haruna and Aki wear (perhaps because she is the student body president) which is the default cream colored shirt but with a maroon ribbon at the middle with a maroon pleated skirt. In season 3, she is often seen in a light blue long-sleeved T-shirt with short blue jeans and a pink scarf tied around her neck. She also holds a light beige colored hand-bag with this outfit, and was a few times seen wearing white sunglasses.
In GO, she has a slightly shorter hair, with the part of her hair parted to the front, and no longer as wavy as before. She wears dark grey shirt covered with a white apron, as well as blue-grey trousers and black slippers. She also wears a pink sash tied up like a ribbon around her waist.
She usually likes to help out, but doesn't like to get her hands dirty. She was shown to have a caring side for Raimon and Little Gigant, as both teams reminded her of Endou Mamoru's unwavering confidence. She's also the girl who has evolved the most in terms of personality, going from all haughty and mighty to caring and dedicated to others, and more specially Endou, given her determination for finding more about the whereabouts of Endou Daisuke, and for finally reuniting grandson and grandfather together through the fullfilling of their common dream, a face-to-face confrontation at the summit of world youth soccer.
In the manga, she is shown to be more forceful and sadistic when it came to disbanding the soccer club, up to a point where she nearly bulldozed the soccer club itself down. Whenever she ends off a conversation, or after she has a point ready to be said so that the soccer club would be disbanded, she laughs "Ho ho ho" and then goes off.
