Summon Night: Swordcraft Story
サモンナイトクラフトソード物語 - Japanese spelling
You aren't alone in the game. As a partner, you will get a Guardian Beast who will offer magic to help you in your battles as well as helping you make your weapons. You can get four different Guardian Beasts depending on your choices, each with different abilities.
Besides the tournament, you need to gather raw materials to make better weapons by travelling through a large dungeon and battling the creatures you find there in a side-scrolling battlefield similar to Tales of Phantasia. You will also have the opportunity to spend time with your summon creature and certain other characters each night. Who you choose to spend time with will affect the story somewhat.
