We investigate eigenstates of a deformed bosonic graphene which might be realized in optical lattices or cold atom arrays.
 We find, in zigzag graphene nanoribbon, a uniaxial "strain" causes strong confinement of the particles in their X point. With uniaxial strain, dispersionless energy bands appear near the X point and the eigenstates are purely one-dimensional. We drive analytical expression for the localization length which shows singular dependence of the "strain" field.
