Howard Link (ハワード・リンク, Howard Link) is an inspector sent to Headquarters, although he appears to be more of Levrier's administrative assistant. He was assigned to keep watch over Allen and follows him everywhere. Link is part of the special combat division of Central's execution squad referred to as "Crow", whose members are said to be trained from a young age. He is armed with a pair of switchblades hidden under his sleeves and can use binding techniques that weigh a target down. He is voiced by Daisuke Kishio.
