Tails and Cosmo woke up the next day and smiled at each other, "Good morning Cosmo." Tails said to her, she simply smiled and they went downstairs for brekfast, however when they could hear what was happining, they became extremely nervous, they heard Lucas scream in rage, "How could you approve!?" they heard another voice they recognized as Earthia's say, "They can be together and you can not change that!" they didn't hear Lucas say anything, so they assumed he was either dead, or too shocked to say anything.
They walked in and sat next to each other, Lucas gave Tails a glare that would've killed him if looks could kill, "I take it you found out?" Tails said nervously, "Indeed, but if Earthia approves, then I have to as well, it's the law that if one approves the other has to as well, but I still hate the idea." Lucas said, Tails and Cosmo got two plates of food and began to eat, under the table as you would expect they were holding hands, but no-one noticed this.
Tails and Cosmo finished first and decided to take a walk, "We'll see you guys later!" Tails called to the family as they left, they went to the top of a cliff overlooking the city, "It's beautiful isn't it." Cosmo commented as the sun rose, painting the sky an orange color, "Not as beautiful as you though." Tails said to her, she blushed a bright crimson after hearing him say that, "T-Thanks Tails, that's very kind of you to say that." she said, Tails just smiled at her and was about to say something else, but they both heard a sound from the forest behind them.
They turned around and saw Shadow standing there, Tails immediatly stood defensively in front of Cosmo, "What do you want Shadow!?" Tails demanded to know, "I intend to make you feel the same pain I felt when I lost my friend Maria." Shadow said grimly, "That was over fifty years ago!" Tails screamed at him, Shadow said nothing but began to walk towards them, Tails and Cosmo began to back away from him, however they soon ran out of ground and were both inches from falling to their doom, Tails decided to attack and he charged Shadow, but he was punched into a tree, "Now to make you feel the pain I did." he said as he continued to walk towards Cosmo.
As Shadow was about to finish her, Tails rammed him from the side and he fell to the ground, "You try and stop me?" he said as a challenge while getting up, "Yes I do!" Tails said before kicking him backwards somewhat, Shadow threw chaos spears at Tails but he dodged, "You've gotten better i'll give you that, but you're nowhere near defeating me!" Shadow said while throwing a punch that hit Tails in the chest, he fell onto his back and groaned in pain as it felt like Shadow had broke his ribcage.
"Tails!" Cosmo screamed, she was clearly worried fro him, "He can't protect you now, and he'll feel the same pain I did, even though he already has once he'll feel it again." Shadow said while he advanced once more, but something grabbed his leg so he looked down, Tails was on his chest and grabbing his leg, "You won't hurt her!" Tails said before yanking him to the ground, Tails got up and once more prepared to defend Cosmo.
Shadow got up and tried to attack Cosmo with a punch, but Tails used one of his tails and blocked it, Shadow tried to punch him but he used both his tails to block the punches over and over again, eventually Tails whipped Shadow with his right tail and he stopped punching, giving Tails the oppurtinity to wrap his left tail around Shadow's legs, he swung him around and around like he did to Hawk in the earth tournament, he eventually made Shadow fly into a tree.
He got up and advanced on the two, "What do we do Tails?" Cosmo asked, "We try and fight him off until we can escape." Tails replied to her, she grabbed his arm out of fear, although she felt better when Tails was protecting her, "Give up Tails, there's no way you can win." Shadow said, Tails didn't budge, he stood there with Cosmo behind him, "Forget it Shadow!" he screamed at his enemy.
"Fine, you'll both die then." Shadow said while throwing more chaos spears, they hit Tails and he collapsed to the ground, he felt more pain than ever before, but he got back up and continued to stand in front of Cosmo, "Will you just die already!?" Shadow screamed, but Tails' reply to that was, "I will not die!" Shadow scoffed and threw more chaos spears at him, however they missed as Tails dodged them, Tails kicked Shadow in the chest and he stumbled backwards away from them.
However Shadow wasn't finished yet, he threw a chaos blast that hit Tails in the chest, he went flying over the side of the cliff and barely managed to hold onto the ledge, it was truly a miracle he even survived the blast itself, Tails pulled himself up and said, "Just leave us alone!" but Shadow said to him, "Not until you feel the pain I did." he threw another attack but Tails dodged, "Please, just leave us alone." Comso said to Shadow, but he ignored her and continued to attack.
Tails punched Shadow in the side of his head with as much force as he could muster, and he fell to one knee gripping the side of his head in pain, as he removed his hand you could see there was blood on his glove, "You furry little bast-" but Shadow couldn't finish the sentance as Tails punched him in the chest, sending him staggering backwards into the side of a tree, "I'll kill you!" Shadow screamed, he charged Tails, but was punched in the chest again, Tails had become stronger from his determination to protect Cosmo, but Shadow could still defeat him easily so he'd have to keep blocking and dodging.
Shadow had had enough of this, he decided to use an attack he hadn't used in years, "Time for you to die!" he said, his hands began to glow yellow and lightining flew out of them, the lightining hit Tails and he collapsed to the ground, "Cosmo, run as fast as you can." Tails said weakly, she didn't want to leave him so she said, "No Tails, i'm staying with you." but Tails wouldn't hear it and screamed as loud as he could, "Just run! I'll be fine but you have to get away from here!" Cosmo said to him, "Just don't die." and ran like he had told her to.
Shadow was about to give chase but Tails said, "Your fight is with me!" while struggling to stand up, "You really want to die don't you." Shadow said, as he was about to attack Tails however something hit him in the chest, Tails had punched him as hard as he could, he kicked and punched Shadow until he was inches from falling, at one punch Tails knocked loose Shadow's emerald, he grabbed it and said to Shadow, "You can either leave us alone or i'll finish you now!" but Shadow was too confident and said, "You don't have the heart, you can't kill a person without becoming a monster." but Tails knew a way around that, "And yet you were artifically created, so therefore your not really a person!" Tails punched him one more time and Shadow stumbled over the side of the cliff, Tails watched as he fell, and he was impaled by the top of a tree, killing him for good.
Tails ran in the direction Cosmo had and found her hiding behind a tree, "Cosmo, it's okay now, I got rid of Shadow for good." he said, Cosmo ran foreward and hugged him while resting her head on his shoulder, "Thank goodness you're alright, but what did you do to Shadow?" Cosmo asked him, "I punched him over the edge of the cliff, he's gone for good." Tails said, Cosmo realized that he meant Shadow was dead and said, "Thank you Tails, now he can't bother anyone again." they walked back to the house and explained the whole battle to Cosmo's family.
"Thank you for protecting my daughter, I guess I misjudged you." Lucas said before going upstairs, Tails and Cosmo spent the rest of the day with each other, when night finally came, they crawled into bed and cuddled closely, "I love you." Tails said to her, "I know." Cosmo said back to him before they both fell asleep.
