That's the only real problem with this series :x Because it's done in arcs, it's hard to really get well-aquainted with the characters. However, there are also the reconquest arcs, side arcs, and cameos to reinforce the characters on occassion. It also helps if you can relate to the characters. Ayumi's, Kanon's, Chihiro's, Nagase's, Minami's, Nanako's, Sumire's, and Hinoki's arcs for instance share a theme of not being good enough of which one (namely me) can relate to. My favorite arcs are Kanon's, Shiori's, Chihiro's, Nagase's, and Yui's.
I definitely just spoiled it, but she's the third arc of the second season :P And definitely relateable as the "girl with average parameters."
Just look at the picture and do nothing more <3

Loli character is cute <3 ^.
YUSH <3 It's so awesome and I don't even know anything about Mahjong. The recap in episode 20 is epic enough to convince ANYONE to watch/read.
