NIFL was first formed shortly after the first Dragon disaster by reorganizing the United Nations troops into a military force that could operate outside of conventional laws and use military intervention to resolve various problems caused by Dragons. NIFL's founders were mainly a faction of people who were displeased by the first 'Gray' Vampire's control over humanity and were hostile towards his successor, Charlotte B. Lord.
NIFL's main duties consist of intervening in border disputes that arose due to the presence of Dragons, pacifying areas that Dragons had traveled through, suppressing terrorist organizations consisted of Dragon cultists and eliminating Ds that were deemed to be 'disasters'. NIFL was also responsible for rounding up Ds around the world and confining them in Midgard, although this changed once Midgard became an independent entity, with the two organizations becoming somewhat antagonistic towards one another. NIFL also took part in anti-Dragon operations, although their insufficient weapons usually had no effect on them.
As of Volume 9, NIFL is close to being disbanded since all publicly known Dragons have been defeated according to Loki Jotunheim's words. Because of that, NIFL openly attacked Midgard with the intent of killing Charlotte B. Lord, the current 'Gray' Vampire.
