A few things to say.
1. You play Skyrim too, Aqua?!
2. I don't watch Soul Eater, so I'm safe.
3. I can think of other ways to kill the other Soul stealers. For example...
15. Have a unicorn impale you in the heart with its horn.
16. Push you into oncoming traffic and have you get run over. Bonus points if it's an 18-wheeler.
17. Pay Pinkie Pie to reenact the Cupcakes fanfic with the person you think took your waifu.
18. Hire an assassin to come into the house of the waifu stealer and kill them however the assassin sees fit.
19. Drop an electric appliance into the waifu stealer's tub during their bath. Death may not result from this, so try again next time if he or she stays alive.
20. Poison their food.
21. Make them enter a fight club, and have his or her first match fixed, where the guy he or she has to fight winds up killing him or her.
22. Drop them into a volcano.
23. Eathquake centered on their house. Bonus points is he or she falls into the fissure created.
24. ELECTRIC CHAIR! *maniacal laugh*
