Kswiss was born in Lavaridge Town in the Hoenn region, to a wealthy family of great trainers. When Kswiss was 10, he received his first Pokemon, a Darumaka his father brought him back from a trip from the Unova region.  Darumaka was kind and loving, but felt a negative aura about Kswiss, and didn't fully trust him at first. With his first Pokemon in hand, Kswiss left Lavaridge town, to challenge the Gym Leaders of Kanto. When he arrived in Vermillion City, Kswiss would come across a Charmander that was being attacked by Team Rocket Grunts, who were attempting to capture it. Kswiss jumped in to try and save the Charmander, Darumaka stood back stunned by this and realised he was wrong about Kswiss and rushed to fight alongside his partner. They were successful in saving the Charmander, however, Charmander had no other place to go, so it wanted to stay with Kswiss and Darumaka. Kswiss would then challenge the Kanto league, using a handful of different Fire Pokemon, realising that he had a passion and love for Fire types. His travels would eventually lead to the Cinnabar Island Gym Leader Blaine, a Fire Type Master. Kswiss was overpowered by Blaine's tactics and strategy, Blaine told him he wasn't ready to master Fire Types, and told him to keep training and try again. Kswiss did just that, he continued through Kanto and acquired 7 badges. He returned to Cinnabar Island to face Blaine once again. Even after everything Kswiss tried, he was still unable to beat Blaine, after the match, Blaine walks up to him and says "You've improved a lot kid.". He helps Kswiss up and tells him "Listen I've never seen someone so determined to try and beat me before, I'm really impressed by you, but you need to refine your skills a lot more. I want you to travel around the regions of the world, and bring me back 8 badges from each region, then come and find me, and face me, and you'll be ready".



Kswiss took on Blaine's challenge and travelled around the other regions of the world, taking names and acquiring Gym Badges along the way. During his travels in Sinnoh, he was given an egg by a mysterious woman who called herself C. When the Egg hatched, the pokemon was a Chimchar, which excited Kswiss, as he had another member to add to his Fire team. During his travels through Sinnoh, he met the Fire Elite Four of the Region, Flint, who battled Kswiss to see what potential he had. Flint noted that Kswiss was too serious during battle and needed to let his Pokemon have fun at the end of the day and love life. Kswiss took this lesson to heart and continued on his journey throughout Sinnoh. Once he finished his trip in Kalos, he decided to return to Kanto to finally face Blaine in a battle. The battle was long between the two, with Kswiss only using Darumaka, Infernape, and Charizard during the battle. Infernape and Charizard had both knocked out Blaine's Ninetails and Magmar respectively but were both knocked out by his Arcanine. When Darumaka was sent into battle, Arcanine laughed at Darumaka, Blaine however, did not make a sound. During the battle, Darumaka did it's best, but Arcanine was clearly the stronger one, Darumaka fell to the ground exhausted and Blaine thought he had won, however, Darumaka began to glow and surrounded itself with fire before it evolved into the powerful Darmanitan. With its newfound power, Darmanitan was able to easily overpower Arcanine and ended with Kswiss being able to finally defeat Blaine. After the battle, Blaine walked up to Kswiss and congratulated him. Kswiss asked if he could stay with Blaine and train to better himself and his Pokemon, to which Blaine accepted.



After some months, Blaine was invited to a Gym Leader conference, and Gym Leaders were to bring a special guest, when he told Kswiss on the day, Kswiss asked "who are you bringing?" with Blaine saying "You, didn't I tell you already?". Blaine attended but forgot to add Kswiss as his guest, which meant Kswiss had to miss out on the battle demonstration due to Blaine's aging mind, much to Kswiss's disappointment. During the conference, the crowd witnessed 2 girls battling, they were the apprentices of Misty and Erika battle to demonstrate their power. Kswiss figured the Water girl would win as she had a Peliper and it had an advantage over the Grass girls pokemon, however, much to the surprise of everyone, the grass girl won.



A few weeks after the conference, a dreadful event happened, Cinnabar Island's Volcano had erupted, Blaine and Kswiss work hard with their Pokemon trying to evacuate as many people and Pokemon from the Island as they could, luckily everyone was saved in the end. With Cinnabar Island destroyed, those who had no place to go settled on Seafoam Island with Blaine. One night Kswiss found Blaine staring in the distance, lost in thought. Blaine turned to Kswiss and told him "There's a new league that has been set up in the Seraphia Region, and they're looking for new people to build it, I want you to go there and help". Kswiss followed his Master's advice and journeyed to the Seraphia Region, becoming part of the league and climbed his way up. One day, there were tryouts for an Elite Four position, which involved a battle test, to see who was the best. Kswiss entered the exam expecting to face some randoms but found that Ventus of the Elite Four was his opponent. The battle between them was long and hard, with Kswiss just winning the battle, much to the shock of Ven and the others. After the exam, the Four Seasons announced the winner, and to his shock, Kswiss was deemed the next member of the Four Seasons, as he was the only one who won his battle. Kswiss can now be found in Magmca Volcano training his Fire Pokemon and awaiting challenges.
