Male. A courageous character, but surprisingly clumsy. He works part-time at a shop but can't cook (he does serving work). He's cheerful but can be quite rude, so he often gets beaten up by other Swamps. Surprisingly, he shows a tsundere side from time to time. His hobby is playing gacha games on his phone; he does it every chance he gets. He is picky about who he meets, so he acts indifferent and prickly toward those he's not interested in. However, he is loyal and playful with close friends. His energy levels are extremely high. He's incredibly cool. His primary weapon is an orange card with a bitten apple logo (he has billions, practically infinite; he uses telekinesis and can fire beams from them. The edges are so sharp and pointed they can slice through things). He also has a blue card with a bitten apple logo that swaps the buffs and debuffs between himself and his opponent. He was once treated as a hero for destroying the God of Materialism, Dareel, but he is gradually being forgotten as time passes. Features: Always smiling, white eyes without pupils -> when he gets extremely pissed off, his eyes turn sky blue instead of white. Very handsome. Takes the form of a white stickman. Height: 158cm Race: A stickman known as a Swamp. He likes Fanta; he'll drink it if it's there. He has a biological grandmother. He has a younger sibling named Kel, but for some reason, Marikin cannot remember them. Marikin's exclusive skill: MARIKIN EX 英雄・再臨 / Hero's Second Coming Entering MODE-EX. "The farce is over..." "This is the sum of my obsession and desire...!" "Don't underestimate a hero!" After saying these lines, he quietly scatters cards and grabs one. The fluttering cards deploy in a circle around him, and both Marikin and the cards are dyed in Sprite Green. The hero who disappeared after the story of 'MARIKIN online 3' ended manifests once again.

Originally had a balloon-like body, but became a Swamp through forbidden human transmutation. It is said he was training as an apprentice under someone to become the ultimate blacksmith. He literally gained a body through human transmutation; before that, he was a balloon-like entity -> literally a balloon. His expression is a constant, unchanging ㆍ×ㆍ. Balloon -> He could speak even when he was a balloon. If he gets angry? The '×' part of the ㆍ×ㆍ expression gets a bit larger: ㆍXㆍ His personality is frivolous and free-spirited. He dreams of being the ultimate blacksmith and sometimes uses an adorable way of speaking (e.g., 'Yup', 'That's right'). He's relatively gentle, but not entirely so; he tends to swear when he gets excited.

A speed freak who boasts the fastest agility among all Swamps! As a pharmacology researcher, Eclair shows outstanding talent in drug manufacturing. It's said she can eat lemons without feeling the sourness. Uses the suffix '-nari' for several Swamps. Sometimes seen consuming marijuana (or smoking opium). Suffers from severe insomnia due to drug side effects, resulting in deep dark circles under her eyes.
