First, get the right costume. Look for a bright yellow Pikachu onesie or make one yourself with yellow fabric and black accents for the ears, tail, and markings. Then, focus on the face. You can use yellow face paint to complete the look. Don't forget about Pikachu's rosy cheeks, which can be added with a bit of pink blush. Also, practice Pikachu's cute poses and expressions, like its shocked face or its happy hopping pose. This will make your cosplay more engaging and fun.
If the cosplayer traveled through the anime novels that they cosplayed, they might find some unexpected plots. For example, they might encounter their own characters and communicate with them.

Cosplay is a form of art and self - expression. The idea of an 'erotic groped story' goes against the very essence of cosplay. Cosplayers put in a lot of effort into their costumes and portrayals, and the community promotes a friendly and safe environment. Such inappropriate stories are not in line with the values of the cosplay community which emphasizes respect for others, creativity, and enjoyment of fictional characters in a positive way.
The role-playing setting 123 referred to the specific role settings that the player or role-player was given in a game or novel.
