This weapon can be obtained by taking a Dark Matter to the blacksmith. It is rare to get from him, and is cursed. The Darkside Sword has ATK+210, unleashes Acron Grief, weak unleash. Perform the following procedure if you struggle to get it.
1) Save in front of Sunshine.
2) Give him the Darkmatter.
3) Step out of town
4) Go back to Sunshine's.
5) If you do not receive the Dark Sword, turn off your game and go back to step 1.
When you have collected ALL of the Djinni from Golden Sun and Golden Sun 2 go to Contigo and use teleport in the circle in the middle of the town. Doing this will give you access to the bonus dungeon. This will not work if you do not have ALL of the Djinni.

On the first floor of Venus Lighthouse (the room with the Psynergy Stone in the middle), save the game and turn of the power(NO soft resets!!), then turn it back on and load the game.
NOW YOU MUST FIRST GET THE PSYNERGY STONE. The first fight you'll encounter is Fenrir+Ice Gargoyle. Make sure you attack in this order: Ivan, Isaac, Mia, Garet(you can change this with djinns if it isn't right), but make sure Garet is still fast enough to attack before the Fenrir.
The Ice Gargoyle should die first.
ROUND ONE: Ivan - Tornado Isaac - Clay Spire Mia - Ice Horn Garet - Flare Wall ROUND TWO: Ivan - Defend Isaac - Defend Mia - Wish(just normal wish) Garet - Unleash Torch on the fenrir
Congratulations!! You've got the Kikuichimonji! It's a Light Blade, so equip it on Ivan, and it unleashes Asura most of the time. You can do this as many times as you want and the Kikuichimonji is worth a lot of money($$$).
