Soul and Maka's Thunder Storm

Soul and Maka have been partners for years, Meister and Weapon, in a world filled with the demonic Kishin.
But the world isn't always so black and gray, and the pair find that everyday life isn't much different than normal people's.
With Professor Stein cracking straight-faced jokes about sex, to Kidd's confusing emotions about the seemingly gender less Crona, this story all centers around one thing: Maka's fear of the thunder.
