From THE iDOLM@STER MILLION LIVE!, it's Momoko Suou with her Monster Girls Series outfit! Momoko is a favourite of mine (if you read her profile, she has to bring around a little stepping stool so she can talk to people at eye-level, that's a power-move) and when I saw she had a new slime-themed costume, I knew what I had to do. Slime is cute.

From Love Live! Sunshine!!, it's Hanamaru's birthday, so she's trying the American diner experince in this waitress outfit! The hamburger might look a bit much but it's based on a scene from the show so don't worry, she'll eat it. Possibly all in one go.
Based on her appearance in The Legend of Zelda: A Libk to the Past (and A Link Between Worlds, and Super Smash Bros. Ultimate), it's Princess Zelda! I particularly like how she's portrayed in Smash- she's got a little bit of sass in that one, so I gave her a little wink here, it's cute.
From the original Pokémon games, it's Erika, the grass-type gym leader of Celadon City! Probably not the first gym leader people think of from this era of Pokémon games, but I really like her design and her team includes Tangela and Vileplume, some of my favourite 'mons. I haven't played a Pokémon game since, uh, the 2000s so I'm very behind (except I know Iono is very good and cool) so when it comes to the Pocket Monsters, this is the era where I live, I guess.
