We report the discovery of a new exceptional young lithium-rich giant, KIC9821622, in the \textit{Kepler} field that exhibits an unusually largeenhancement of $\alpha$, Fe-peak, and \textit{r}-process elements. Fromhigh-resolution spectra obtained with GRACES at Gemini North, we derivedfundamental parameters and detailed chemical abundances of 23 elements fromequivalent widths and synthesis analysis. By combining atmospheric stellarparameters with available asteroseismic data, we obtained the stellar mass,radius, and age. The data analysis reveals that KIC 9821622 is a Li-rich(A(Li)$_{NLTE}$ = 1.80 $\pm$ 0.2) intermediate-mass giant star ($M$ = 1.64$M_{\odot}$) located at the red giant branch near the luminosity bump. We findunexpectedly elevated abundances of Fe-peak and \textit{r}-process elements. Inaddition, as previously reported, we find that this is a young star (2.37 Gyr)with unusually high abundances of $\alpha$-elements ([$\alpha$/Fe] = 0.31). Theevolutionary status of KIC 9821622 suggests that its Li-rich nature is theresult of internal fresh Li that is synthesized through the Cameron-Fowlermechanism near the luminosity bump. However, its peculiar enhancement of$\alpha$, Fe-peak, and \textit{r}-process elements opens the possibility ofexternal contamination by material enriched by a supernova explosion. Althoughit is less likely, planet accretion cannot be ruled out.
