No point in talking about a harem when Nikaidou would crush anyone that tries to get close to Tadokoro. I think the only thing that could stop Nikaidou is another Nikaidou.
And even then they'd probably just work together in the end.
At this point I'm not sure if Nikaidou's power is innate or if it just comes with liking Tadokoro-san. It seems everyone that likes Tadokoro-san gets a coolness upgrade.
I want to join you guys by complaining about the fact that the Chinese hero is once again portrayed as a effemine Kung-fu fighter, but I just don't have the heart.
I like cute characters and Meng Long is hella cute.
