Origin
Pallet Town, Kanto
Daisy Oak is the older sister of Blue, and the granddaughter of Professor Oak. She is known as May in The Electric Tale of Pikachu manga. In Pokémon Red, Blue, and Yellow, as well as in Pokémon FireRed and LeafGreen, Daisy gives the player a Town Map (despite her brother telling her not to) if he or she visits her after receiving a starter Pokémon. She gives free grooming to one of the player's Pokémon in the Generation II games once per day between 3 and 4 PM, and in FireRed and LeafGreen every 500 steps once the player has entered the Hall of Fame. Also in FireRed and LeafGreen, after the player has entered the Hall of Fame, Daisy will tell a player how happy their Pokémon are. She's well known for being adored by all kinds of Pokémon. It is said that when she's around, even the most ferocious Pokémon calm down. Daisy enjoys tea every day, and buys hers from the Celadon Department Store. She's also a champion Pokémon Coordinator, having won the Spring Pokémon Contest some years back. In her house, there's a photo of "the lovely and sweet Clefairy." In Pokémon HeartGold and SoulSilver, she gives the player Blue's number so they can call and arrange a rematch with him at the Fighting Dojo in Saffron City. She will only share this once she has given seven groomings and been shown one Pokémon with maxed friendship. Also returning from previous generations, Daisy, still located in her home of Pallet Town, will groom one of the player's Pokémon for free once daily between 3:01 and 4:00 PM. As in Generation II, it will raise a Pokémon's friendship greatly, but it will also raise the Pokémon's Contest condition by 32 Beauty and 22 sheen. This is not displayed anywhere in-game, and the Pokémon must be seen from the point of view of Diamond, Pearl, or Platinum to notice. Despite this, a Feebas whose Beauty is maxed out this way can evolve into Milotic. As a reference to her enjoyment of tea in Generation III, a large mug of tea sits on her table. She will also mention that she "usually has tea about this time" if she is visited between 15:01 and 16:00 in Generation IV.

Pokemon (Root Series)
Pokemon are peculiar creatures with a vast array of different abilities and appearances; many people, known as Pokemon trainers, capture and train them, often with the intent of battling others. Young Satoshi has not only dreamed of becoming a Pokemon trainer but also a "Pokemon Master," and on the arrival of his 10th birthday, he finally has a chance to make that dream a reality. Unfortunately for him, all three Pokemon available to beginning trainers have already been claimed and only Pikachu, a rebellious Electric type Pokemon, remains. However, this chance encounter would mark the start of a lifelong friendship and an epic adventure! Setting off on a journey to become the very best, Satoshi and Pikachu travel across beautiful, sprawling regions with their friends Kasumi, a Water type trainer, and Takeshi, a Rock type trainer. But danger lurks around every corner. The infamous Team Rocket is always nearby, seeking to steal powerful Pokemon through nefarious schemes. It'll be up to Satoshi and his friends to thwart their efforts as he also strives to earn the eight Pokemon Gym Badges he'll need to challenge the Pokemon League, and eventually claim the title of Pokemon Master.
