Thanks for the update. Based on the LIMITED info we were shown, new savior might be
a. Love Rival
b. Tsukina acquaintance
c. The repeat of him being passionate might lead to a conflict where he WON'T respect Tsukina's decision of living a life of hermitage (not to mention the difference in age/values), something like Tsukina is the ultimate defense (Barrier magic) and he was given the strongest offensive magic
