"You can't be more popular than me. I'm the main character of this franchise and stuff!"
"Actually, I heard this game is supposed to come with some cool bonus items."
"Nep, Nep Nep Nep Nep Nep Nep, Nep Nep."

Big Neptune
Wow, you have 'Nep' in your name, too?! Crazy!
"Maybe I'll catch them to put in my specimen book."
"Alright, into the specimen book!"

Nepgear
Would you like to take a small break? I brought snacks with me."
"Like a bunny!"
Don't you think games are way more fun and rewarding when you don't cheat at them?"

Uni
"You've got a text. I'm curious to know who it's from."
"Your phone's ringing. You better pick it up quick or they'll hang up."
"It's nothing special, but I'll still give you a compliment. You're such a good kid."
