I know, Riku's character looks stupid and not like the real Riku,but C'mon! It's virtual characters they made!

Haru/Riku-Twin Blade

Midori/Kairi-Heavy blade

Izumi/Namine-Long arm(I know she looks more like a wavemaster!)

Yes, Namine is SUPPOSED to be a long arm(the ones that use the spears/lances/whatever)but she came out looking more like a wavemaster...
