  We propose a new kind of inverse seesaw model without any additional
symmetries. Instead of the symmetries, we introduce several fermions and bosons
with higher $SU(2)_L$ representations. After formulating the Higgs sector and
neutrino sector, we show that the cut-off energy, which is valid to our model,
is at around TeV scale, by examining behavior of $SU(2)_L$ gauge coupling. Then
we show the testability of our model at collider physics.
