Comment by Harlock on The World Of Otome Games Is Tough For Mobs - Chapter 74

I do not even remember him going on a dungeon, in any case there is one OP ship but another reincarnator gets it, to her bad luck it is not as nice as luxion. Leon will challenge that jerk who took his stuff to a fight and then Luxion will simply use everything to attack the jerk's country under the jerk's name and win! That is what i remember from the novel.

New sacred tree sapling?

This dungeon is where they will collect the new sacred tree sapling in order to bait the others six houses in this Pierre mess. Using the sapling Pierre will want it and Leon using that against will bet in a deal against him to fight mech against mech but Leon the badass he is will fight without a mech but with specially made gloves. The mech Loen is going to fight is his own mech turned into a spiked head punk style mech. For anyone wondering the bet was if Leon lost he would give Pierre the sacred sapling and if Pierre lost, he HAS to give back Leon's Airship immediately.

Luxion is just faking switching sides, he is pi** with Leon but he can't really switch sides because he serves old humans, not the new magical ones. I can't remember exactly if Leon knew about the fake betrayal. but they used it to extract info and make the families make mistakes.
