Fuyuki Hinata (日向 冬樹,Hinata Fuyuki) is a protagonist of the series Keroro Gunso and related media. He is the partner to Keroro and the younger brother of Natsumi Hinata.
Fuyuki is polite, compassionate, paranormalist, happy, forgiving, scary, reserved. He is the opposite of his sister Natsumi in many ways. First of all, their personalities vary widely, since Natsumi tends to be very outgoing and quick-tempered as well as strongly athletic, whereas Fuyuki is much more calm and reserved, and tries to avoid fighting and physical education as much as he can, but does unleash a full body of bottled anger that even frightens Natsumi when he is uncharacteristically furious. Also, while Natsumi's name means "summer beauty" and has red as her symbolic color, Fuyuki's name means "winter tree" and has blue as his symbolic color. Fuyuki is an obsessed expert of the paranormal and science fiction, and for unknown reasons, he tends to encounter many of the bizarre creatures that he knows very often. His appearance reflects that of a normal Japanese boy; black hair (tinted blue), dark blue eyes, and an average figure.
Fuyuki has a close bond with Keroro that exceeds space. When Keroro is about to completely destroy Earth, he simply needs to say that if the Earth is blown away, all the Gundam factories will be too, and Keroro will stop, as Gundam is one of the sergeant's favorite hobbies. Alternatively, Fuyuki reminds Keroro that they are friends, and that usually causes him to stop whatever he is doing.
Alisa Southerncross uses Fuyuki as bait to attract aliens, or "dark" or "cursed ones", as she and her father calls them. Although any other person would absolutely hate this position, Fuyuki forgives Alisa about this, since Alisa was actually a puppet and her father thought that by hunting aliens, she would eventually gain humanity.
Despite his unearthly patience with the insanity that seems to flower in the wake of Keroro and the others, Fuyuki does have a temper. When his temper is up, which admittedly takes a lot (because it barely shows up), Fuyuki is capable of terrorizing not only Keroro and the platoon but his sister and others as well. When enraged, Fuyuki's face is never shown, just the reactions of those around him for comedic effect. His first appearance of anger is shown in:
Anime: 1st season, Episode 23 at the end of the episode.
Manga: Volume 9, encounter LXXI after finding his package gift from Akina.
While not known for sports, Fuyuki is surprisingly good at bowling to the point that even Natsumi admits that she cannot beat him.[1] When he was younger, he hates the school's sport festival and drew a Rain Monster, praying for rain so that it would be canceled school sports day would be canceled.
However, sometimes Fuyuki can be quite irritating by being oblivious to the feelings of others such as Momoka and Keroro, and does actions which could possibly irritate them even more.
After first discovering Keroro hiding in his bedroom wall, Fuyuki has taken an immediate interest to him and after defeating Keroro with the Keroball, Fuyuki holds custody to it. Since then, Fuyuki and Keroro have had a start to what would become a great friendship. Despite his sister's dislike to Keroro, Fuyuki affectionately calls him 'Gunso' and would help him from shopping to Keroro's platoon's plots to world domination (although this rarely happens and is often done when Fuyuki was unsuspecting). Their strong brotherly relationship helps overcome many obstacles, notably in the first movie and the finale of the first season.
Momoka has always had a crush on Fuyuki, although her (often overactive and expensive) plans only work with minimum success. Still, she works hard along with support from the Keroro platoon (mostly because of her close relationship with Tamama and Keroro's interest to Momoka's incredible wealth) to draw Fuyuki close to her. Fuyuki only seems to think of Momoka as a good friend, but seems to also have an interest to her.
There is a hint that Fuyuki has some kind of love interest to her. In episode 296, Momoka bought a medicine from Kururu and it spread through the Hinata house, if a person smells it and looks to something, immediately will love it, but when Momoka woke up Fuyuki to see her, Fuyuki didn't love her. Kururu explains later that the medicine doesn't work if the person in front of you already loves you, so Fuyuki possibly likes Momoka.
Fuyuki's first meeting with Alisa was anything but welcoming. Alisa's ability to turn Fuyuki's friends into stone was frightening, and she also kidnapped the Keroro platoon and Fuyuki because of his 'special interactions to dark creatures', which are his strong friendships or meetings with the aliens. Eventually, before Alisa had a chance to eat the platoon, she is defeated by Fuyuki, Natsumi, and Saburo. Despite their unpleasant first meeting, Fuyuki forgives Alisa and wished to become her friend.

Weaknesses
Fuyuki is physically weak and bad at sports in spite of his known family being otherwise known as fit athletes. His worst sport is swimming, which he is completely unable to do during most of the series. Even Myou Kaneami notes that her power of awakening hidden abilities might be useless to help him swim if he has no talent for it at all.
However, once bonding with Io's soul in the manga, he's able to run and swim. Even after losing that power, he was able to jump to carry Dororo out of the way of Aku Aku's attacks. It's not clear at this point if he surpassed his physical weakness or if it was just a one-off incident.
According to episode 72 of the anime, he is afraid of beetles and according to episode 123, his worst fear is a vaulting box. Fuyuki is also so obsessed with the paranormal, and upon finding a possible artifact, he can go into fanboy mode ignoring everything else around him.[2]
Etymology
Fuyuki literally means "Winter"-Fuyu, "Tree"-Ki
