Quote:We are talking about Laharl here... he can take down literally 2 million space going battleships... single handed... and not be phased or winded. Laharl has different standards... Laharl declaring someone/thing a vassal is also not something they get a say in. He is rather like Monkey D. Luffy in that. He declares you his minion and you end up his minion. Laharl probably just read the name Kyuubi as a powerful demon and decided it was his vassal now. He does stuff like that.
I mean, Kyuubi ... a vassal? Er. No. Just no. Also ... why in the name of all that's unholy does the author insist on basing this thing around Konoha still? It's just so ... vanilla. And boring. I want to see Naruto infect the Netherworld with ramen-mania, damit! Among other things.
The Kyubi can take out villages of ninja (barring sealing) yes... however power wise Flonne could do that on her own. The power scale of demons given here is genin are level 15-20. Jonin are level 70-75 range. If the 3 legendary ninja are above 150-200 I'd be suprized. Kyuubi is like level 500. Demons of Kyuubi size are canon, like the level 750 that splits into 10 level 75s.
Granted the story itself is a taking place during the second or third arc of Naruto. So yes... its going to be somewhat dull power wise... a crossover like your talking is after Sasuke leaves. Maybe their fight attracts Laharl's attention he snags Naruto for the 3 years of training. That would be more your taste.
The story that is written is more what happens when Flonne and Etna bully Laharl into doing things their way (grant a certain Prinny planted the idea). Also I can see Disgaea happening is the Naruto-verses Netherworld. Would explain Flonne's ninja fixation. Earth is just in the same universe... the Earth fleet got the wrong Netherworld.
I understand your 'vanilla' complaint... but Laharl does declare uber beings his vassals as a battle cry.
