As mentioned, the first half of this activity was first posted by Yanaa as a simple game and I have just made it shinier with some different characters.
I used this the lesson before my 5th graders really got into the meat of making their own Who Is This cards so they they could understand what the purpose of the cards was and how to give leading information. In all the classes I ran this with I did a quick run through of the pronouns they're learning, reminded them of the third-person 's' (e.g. he likes), and made sure they knew how to work with 'can' as their grammar before I started in on the activity.
Part 1 of this is a 3-hint quiz for anime characters and famous people using short hints that model the grammar for the students. I tried to make the mini-quizzes harder as they went along so the kids weren't breezing through them in seconds and to encourage them to thinking harder as they become more familiar with the game's framework. There are four of these and they're characters/people I know my students are familiar with, so feel free to change the answers as you see fit. You can also duplicate these sections and add more or less of them if you wish!
Part 2 is getting the kids to move from guessing to introducing. They're shown a character on the slide and given some prompts to ask what they can do, what they like, what kind of person they are etc. I used Japanese here so they weren't getting overwhelmed but delete it at your discretion. Again, feel free to change these characters out, I'm trying to earn cool points with the sprogs here haha. This part works well if you're getting the whole class to contribute so that they can suggest things at random and come up with a bunch of different answers before the next (model) slide is revealed. This way it shows there's not one 'correct' answer and that there are multiple ways to introduce the same person. There are two of these. After that, it's the students' turn to make their own. They should choose a person/character and introduce them as they've just heard modelled.
Regardless of whether you use the whole thing or just the game bits, I hope this is useful for your classes!
