Osteoclast (破骨細胞 はこつさいぼう?) is a character that exclusively appeared at Itsudemo Hataraku Saibou game.


An osteoclast (from Ancient Greek ὀστέον (osteon), meaning 'bone', and κλαστός (clastos), meaning 'broken') is a type of bone cell that breaks down bone tissue. This function is critical in the maintenance, repair, and remodelling of bones of the vertebral skeleton. The osteoclast disassembles and digests the composite of hydrated protein and mineral at a molecular level by secreting acid and a collagenase, a process known as bone resorption. This process also helps regulate the level of blood calcium.
