  We theoretically investigate the spectral properties of a quantum impurity
(QI) hosting the here proposed {Majorana-Ising-type quasiparticle (MIQ)
excitation}. It arises from the coupling between a finite topological
superconductor (TSC) based on a chain of magnetic adatoms-superconducting
hybrid system and an integer large spin $S$ flanking the QI. Noteworthy, the
spin $S$ couples to the QI via the Ising-type exchange interaction. As the
Majorana zero-modes (MZMs) at the edges of the TSC chain are overlapped, we
counterintuitively find a regime wherein the Ising term modulates the
localization of a fractionalized and resonant MZM at the QI site. Interestingly
enough, the fermionic nature of this state is revealed as purely of electron
tunneling-type and most astonishingly, it has the Andreev conductance
completely null in its birth. Therefore, we find that a resonant edge state
appears as a zero-mode and discuss it in terms of a poor man's Majorana[Nature
614, 445 (2023)].
