A Look at This Adorable Trio in Action
This sticker pack is filled with personality, perfectly capturing a range of daily emotions and expressions. The collection features the main cast in all sorts of relatable situations. In the top row, we see Mike, the charming cat with glasses, giving a big thumbs-up with a sparkle and the Japanese text for “Nice!”. Next to him, Zeny, the little green character, is practically vibrating with shock, with “Eeeeeh…” written above him in a classic expression of surprise. Then there’s Lop, the red-haired girl, looking totally relaxed on a beanbag with some snacks, casually saying, “Is that so?”. To round out the top row, Mike makes another appearance, this time as a lucky waving cat holding a gold coin to say a heartfelt “Thank you.”
The fun continues in the bottom row. The whole gang—Lop, Mike, and Zeny—peeks out from the side of the screen with a playful “Chiratto,” which is the sound for taking a quick glance. Then, a cheerful Mike is seen dancing with musical notes floating around him as he wishes everyone a “Good morning!”. In a hilarious twist, Zeny suddenly transforms into a super-muscular version of himself, flexing his biceps and boldly declaring, “Leave it to me!!”. Finally, the set ends on a sweet and calming note, with Mike peeking out of a cardboard box to say, “Otsukaresama,” the perfect Japanese phrase for “Good work” or “Thanks for your efforts.” It’s a fantastic mix of cute, funny, and useful reactions.
Meet the Mercari Crew
So, who are these characters lighting up our chats? Each one has a distinct personality that makes the sticker set so dynamic. They aren’t just random drawings; they’re the official faces of the Mercari brand.
Mike, the Dependable Cat
First up is Mike, the white-and-brown cat with the signature round glasses and red bow tie. He’s described as being earnest and kind. You can totally see this in his stickers, from the polite “Thank you” to the enthusiastic “Good morning!” He’s the reliable friend in the group, always ready with a positive gesture or a word of encouragement.
Zeny, the Wild Card
Then we have Zeny. This little turquoise creature is the life of the party, described as energetic and wild. His personality shines through in his dramatic reactions, like the flustered “Eeeeeh…” and his sudden, hilarious transformation into a muscle-bound powerhouse. Zeny is the character you use when you need to express big, over-the-top emotions.
Lop, the Cool Trendsetter
Rounding out the trio is Lop. With her stylish red hair and laid-back attitude, she’s characterized as cool and fashion-loving. Her sticker, where she’s just chilling out on a beanbag, perfectly captures that effortless, relaxed vibe. She’s the cool-headed one in the group, bringing a touch of chic calmness to the conversation.
The Brains Behind the Brand
These stickers are more than just cute pictures; they’re a clever piece of branding from Mercari, Inc., the company that owns and operates the massive e-commerce platform. By creating official mascots, Mercari makes its brand more personal and approachable. Instead of just being a faceless app for buying and selling goods, it becomes a platform with a friendly, recognizable crew. This is a popular strategy, especially in Japan, where character mascots, known as yuru-chara, are a huge part of corporate and regional identity.
The company holds the copyright to “Mike, Zeny, and Lop’s Cheerful Days,” ensuring these characters remain exclusively associated with their brand. Offering them as free stickers on LINE for friending their official account is a brilliant marketing move. It increases their follower count, allows them to push updates and promotions directly to users, and builds a positive association with their brand every time someone uses a sticker. The limited distribution period, ending on September 23, 2025, adds a sense of urgency, encouraging users to download them now. It’s a win-win: we get fun, expressive stickers for our chats, and Mercari gets to build a stronger, friendlier connection with its community.
