tamarakko:

a quick summary of some particular traits that didn’t change through the adaptations

osomatsu: very playful but very malicious. always the worst when it comes to poke fun at others
karamatsu: the clumsy, unlucky one 
choromatsu: ALWAYS AGGRESSIVE. resorts to violence a lot. 
ichimatsu: shy and awkward. despite being named after one (ichi), he doesn’t like being in the center of the attention
jyushimatsu: an easy going (and weird) personality always accompanied with a big, open mouth
todomatsu: a spoiled crybaby, pretty fitting to his title of the youngest kid
