Hikari Saitou from Magical Girl Opal, a game by developer Moe Kobou/Moe Workshop
After the streak of riviera and yugioh cards, time to go back to h-game characters, and it's another Hikari to the list (if you're counting Dawn)
This game is similar to Celesphonia where you can have your character do odd jobs to earn money to buy items, while also having a time limit of sorts to fight the villians, though it's a bit on the easy side because each dungeon has a level that once you reach it, you can skip the encounters while still earning exp (though I accidentally turned that off when I equipped an item and only found out about it after three dungeons I believe)
