Tsunayoshi Sawada.
If Tsuna were to be completely honest, it was quite the workout to have his storm guardian with him, twenty-four seven. He was too impatient, too hot-blooded, too short of temper to be anyone near soothing in presence. Regardless, Tsuna wouldn't ever exchange his so-called "right hand man" for any other; because he knew, that despite the impatience, hot-bloodedness, and short temper, Gokudera Hayato was the most passionate of all in the family.
He is impatient because he cannot withstand waiting for the enemy when something precious of his is harmed. He is hot-blooded because he cares deeply for his ties with others, and would lay down all of himself to keep them safe. He is short-tempered because he cares. So much that it breaks all of his stable mindset. So much that he can't help but be angered because they are my most important people so back off.
To Tsuna, Gokudera Hayato is the one person he can rely on to be the most passionate, to be the anger, to be the fangs, to be the one to keep the family alive.
Takeshi Yamamoto.
Teasing Hayato is amusing to boot. He's too serious, can't make a joke, and definitely doesn't know how to relax. It makes him opposite to Takeshi, because really, who is Takeshi to not smile and relax? So it's ever fun to keep Hayato on his toes.
But despite all of the teasing, Takeshi truly does trust the boy with all his heart. He is, undoubtedly, one of Takeshi's best friends, and he's sure that if anything were to happen to himself, Hayato would be the first to defend him. It is what makes Takeshi calm in battle, ever moving forward, because he knows that there will always be someone behind him, watching his back.
To Takeshi, Gokudera Hayato is his equal in battle, his best friend, his best rival, and the epitome of the ferocity of the family.
Ryohei Sasagawa.
If Ryohei were to say about strength in the family, it would definitely be Sawada as number one to the extreme. Nevertheless, Ryohei knows that Sawada is not the most vicious. He knows that that title lies with Gokudera, because to him, it is obvious that passion and ferocity flows out of him like water. To Ryohei, even Hibari doesn't compare when it comes to viciousness to the extreme.
Gokudera's viciousness allows for Ryohei have a reason to bare his fangs too, because he knows if he fights with this ferocity, there is nothing that is able to stand ground against them.
To Ryohei, Gokudera Hayato is truly the storm of Vongola, raging on, ever thundering of power and strength, the natural shield to the castle that is the Tenth generation family.
Lambo.
Lambo is only five, so he doesn't see any deeper than whatever Hayato puts on the outside. He's Stupidera, and really, what else could he be? Lambo doesn't particularly enjoy being with Stupidera, because he just doesn't get what it means to be fun. He doesn't like being with Stupidera because he's always scolded on those outings, and to Lambo, that's all that matters.
Despite that, it is still reassuring to see that silver hair in front of him when there are scary people, and there's always a sense of safety watching the back of the man whom Lambo supposedly hates.
To Lambo, Gokudera Hayato is a nuisance of an older brother, but an older brother that he knows he can rely on, and knows loves him with all his heart, however much he scolds Lambo.
Kyoya Hibari.
Kyoya doesn't put Hayato anywhere near a worthy opponent on his dueling list. He would never put an herbivore on his sacred list. But that doesn't mean Kyoya can't see what the others see in Hayato.
In his usual manner, no, the herbivore doesn't compare to Sawada Tsunayoshi or the pineapple illusionist, but Kyoya isn't blind. He knows that if an herbivore is angered, or its herd attacked, it could easily match a carnivore. He knows that no matter how weak Hayato may seem, if any idiot so much as touches the family, the silver-haired herbivore will grow fangs and claws.
To Kyoya, Gokudera Hayato is still an herbivore, but not one who needs protection. To be honest, if Kyoya can force that ferocity out of the herbivore, he just might, just might, make it onto the list of opponents.
Mukuro Rokudo.
What a boring man. That was Gokudera. No more, no less. Mukuro has no idea what the heck makes everyone turn and run when they see silver hair and red flames. He feels not one drop of strength in the hot-blooded man. Smart? How could he be? He's much too short of temper for intelligence.
But when he feels this boring man tense up during Vongola meetings, he can't help but follow suit. It takes Mukuro a while to understand this power, this true intelligence to judge the goodness and strength of others. It takes Mukuro while to see why the storm is known for intelligence.
To Mukuro, therefore, Gokudera Hayato is a judge, to all people, and is the one that would not fail to see any one waver of heart in the goodness of a person. He is the one that Mukuro will always trust to find sinners worth punishing, because that was his intelligence.
Gamma:
Gamma wonders: what is it that makes this brat feared in the world of the mafia? He's no thinker in battle, nor is he physically the strongest. Gamma doesn't understand, until he sees the boy fighting next to the rest of the Vongola.
When the boy is standing next to his beloved family, he changes. He becomes from a storm to whirlwind of mass destruction. His intelligence is now tenfold, and his nerves become that of steel. He's no longer a brat, but is now someone that is worthy of his reputation in the underworld.
To Gamma, Gokudera Hayato is the hurricane that sweeps all of its obstacles away, leaving nothing but its center, its heart.
Bianchi.
Hayato is not as strong as everyone perceives him to be. He is not an everlasting storm. He is only a boy, keeping his façade only to be sure that his family would not see the weakness in his heart. He is strong, but not eternally. He will fall, one day, broken by his own silence, and Bianchi knows that that day is fast approaching.
However, Bianchi is not afraid. She knows that her brother will pick himself up, and that the entirety of the family will help piece him together when that time arrives. Her brother is still strong, and she's sure that strength will keep him running.
To Bianchi, Gokudera Hayato is her beloved little brother, prone to self-destruction, but not weak of heart. He is strong, she knows, and that this is what makes the others run ahead, unafraid of the enemies behind them, because they know that the bullets wouldn't reach their backs. They know that the storm will be there, its powerful winds ready to blow all weapons of all kinds away from them.
Gokudera Hayato:
The passionate, the ferocity, the viciousness, the fangs, the intelligence, the hurricane, the storm.
