Not_Kuromaku

One day, Kuromaku started drawing, but he couldn't do it, which often made him nervous and angry. He gave it up and promised himself that he would pick it up again someday, with renewed vigor. When that "someday" will come is unknown.[3]
Kuromaku never drinks tea from bags and considers tea from bags to be the height of bad taste.[4]
Kuromaku's favorite tea is jasmine green tea, although he doesn't know much about the different types.[4]
Pik taught Kuromaku how to make pancakes, the favorite (and often only) breakfast food of the Clubs[4].
Kuromaku has unwittingly adopted some of Romeo's habits and speech patterns from his frequent interactions with him (for example: the habit of sometimes addressing clones as "you", deliberately stretching words to achieve a certain effect, and the same sitting position with his head slightly raised)[1].

Kuromaku tried playing every possible instrument.
Kuromaku doesn't understand sarcasm[2].
Kuromaku loves water treatments and devotes a lot of time to them[3].
Kuromaku loves bath bombs and bubble baths[3].
Kuromaku has a yellow rubber duck named Friedrich[3].
Kuromaku loves rock music, but prefers to hide it from others.[3]
At one point, Kuromaku offered musical lessons, which he greatly appreciated, but not everyone was able to withstand his constant stream of nagging, criticism, and pressure. The only one who remained to study piano with Kuromaku was Dante[3].
Kuromaku tried to teach Zonta an instrument, but he couldn't learn any. Eventually, he gave up and gave him a kazoo.[3]
Kuromaku gave each of his instruments a name. For example, he named his first flute Aelita, and one of his double basses Leonard.[3]

Kuromaku has a rather complex personality. He's an irrational creative individual, an accomplished classical musician, an egocentric, a perfectionist, and an idealist who expects high results from himself in everything he does. This leads to his love of lecturing everyone around him. Kuromaku is a very sensitive person, which is why he tends to somewhat exaggerate his emotions towards anyone or anything. He believes that art, whatever its form, should live on and convey its meaning to others (except for what he dislikes).
