Solomon

What can an older sister do to save her beloved from a harem? Anything! Sola is serious. The dragon won’t see her erlines. The princess of demons won’t allow a love-loving keeper of concubines to use her little sister as an incubator… even if she has to damage her own soul for it!

“Want to steal the demon princess!? Over my dead body! Though… first try to compete with my gift!”
