description The logic sqŁ<sup>*</sup> is closely related to complex fuzzy sets. In this paper, we continue our study on sqŁ<sup>*</sup> by establishing a system that includes all formulas with values <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mn mathvariant="bold">0</mn></semantics></math></inline-formula> in sqŁ<sup>*</sup>. This system has paraconsistent formulas within sqŁ<sup>*</sup>. Moreover, we show that this logical system is both sound and weakly complete.
