Frizzled hair and ice cool eyes.... a young female delinquent with a rebellish attitude at first glance. Machi is an expert in the art of deadly needlework. Her nen is shaped into thin wispy-long threads which she uses in a variety of ways-- in healing wounds, repairing back dislodged limbs like what she did for Hisoka, or like a hangman's noose that strangles enemies with a tug. A death angel that is able to grant the wish of life or death.
What's her relationship with Hisoka? Hisoka seems to have an occasional interest with her, although it's hard to see whether it's genuine, given Hisoka's unpredictability. Machi also doesn't appear to be interested a single bit, spurning his advances on all occasions.
