Comments of chapter undefined of I Am Fugaku Uchiha

this entire plotline since he decided he wanted a flying summon is kind of ridiculous. fugaku leaves the frontline forces for weeks, or over a month, with what excuse? and now somehow he and jiraiya are trying to storm hozuki castle for this same penniless princess? i thought this author had a good handle on reasonableness by the mc, but it seems that this fic too, is a failure in this regard.
