Wait what...?
But I thought for sure the few last chapters were hinting for yuri in the near future....
We're talking about Shou, Legendary Master Troll and Supreme Lord of the Dark Arts of Deceit, tracing and vagueness.
We can't be sure of anything. For all we know in the next chapter they can be together as romantic couple, Keiko could be back with her boyfriend and Ran paired with... er... the perverted boob-loving kid, or a thermonuclear device fall and everyone die.
