Daitaro (long hair) and Daiki (Short hair) Along with Hachi (the puppy) They are the eldest (12 year olds).

Daiki is short tempered and almost always looks irritated. He can often be seen with Daitaro, as they are unapologetically together most of the time. Mitsuru and Masaru often tease them about it, thing that can actually cause Daiki to feel embarrassed and move away from his twin (he'll eventually come back to his side though)

He is the less affectionate from his brothers, though, Daitaro and Masaru seem to tease him about his 'subtle' signs showing he cares. Daiki has a talent for music and can be seen playing his flute. Though he'll probably stop playing if he catches his siblings staring.

Although he has high marks at school, in words of Mitsuru, he is incredibly dumb when it comes to understanding his own feelings.

------

Daitaro is patient, understanding and cheery. He has an incredibly weak spot for his brothers, as he is too sweet towards them (to the point of causing them second hand embarrassment). He rejoices in embarrassing his brothers by telling them how much he loves them and pampers them as much as he is able to.

He is generally very hard to anger.

Besides his nice qualities, he can be very intimidating and as his siblings state 'they wouldn't want to see him truly angry'. (Though Mitsuru would digress)

He carries the nickname "Rage", and though it usually doesn't bother him, he hates anyone else but his brothers using that instead of his name.
