Traveling with Pokémon in Hunter World

When she woke up, a letter from three years ago broke Lucy's peaceful and desperate life. She had parents she hadn't seen for many years, and a robot that behaved strangely. What was going on? Why did I end up in a completely strange world again out of nowhere! Why did my robot become alive? But Maomao is really good~ Who can tell me what the hell this big fat purple guy is! (Ooc warning, favoring the group, be careful to avoid lightning, I really can't write an introduction, the heroine is 12 years old, doesn't understand anything, there may be some witty plot, cp Killua)
