Feels more like she's going to protect the people of her family's territory more then because she wants to protect her family (her "being a true noble" speech kind of clarify that) her family is a secondary goal, as in "an acceptable lost compared to the people of her old family's territory!"
The "Drama" was that she knew as Van's Fiancee, she isn't OFFICIALLY married into HIS family yet, so doing this without anything of his (The dolls he made clear are HERS so they don't cound as him "helping her" since they were always a gift for her private use and self-protection) will be seen politically as "her defending her home as a member of her family" NOT as his!
She hates herself for pushing Van back from this as he loses a political advantage against her father because of it (It's already a given anyway that her family will likely lose more of their territory to Van anyway as the "Short Straw" once the King and PM make the arrangements for him. IF Van had been allowed to save her family)
Honestly it shows her as a VERY GOOD WAIFU since she doesn't wholely depend on Van to aid her 24/7 100%! As his future Bride, she can do her part as well! Leading the Adventurer's she hired and her performance with the Dolls as even if Van made them, they only work for Puppet Magic users! (Also a GOOD display that Puppet Magic which already showed it, but the doll has to be HUGE to make this VERY CLEAR to even the most ignorant, aren't just "people who seize control over living things with it! It helps BURY the "Creepy reputation" that the Magic has with something VERY impressive, same with Van's own magic! As said the ONLY REASON they have bad reputations is no one BOTHERED to pursue any other way they could be used, mixed with ignorance meaning, though Van unlike Aria is more a MUTANT with his magic type! Aria's puppet magic always had this potential, just cause Puppet Mages are the only ones who can use the Dolls, doesn't mean they can use them BY DEFAULT as alot of this was Aria's OWN skill and training in this level of control, something that was "left in storage to rot" when her mother DISCOURAGED her from pursuing any further in improving out of "Shame" being reminded again she was a "creepy Puppet Mage!")
In this form, she will do to her parents (not intentionally, but you know it will happen) what Van did to his dad (the same, unintentional LOL) and it's "saving the day, despite to the parents being the LEAST LIKELY, hell they thought they were "living in misery barely surviving" (Reminder that Arti's parents just like Van's dad and the IMPERIAL INVASION FORCE FOR THAT MATTER assumed Van's Territory was just a "Barely surviving Village in nowhere's-ville!" A Place to throw "unwanted noble children you HOPE die of something there naturally so then you DON'T get called a "Kin Slayer!" Aria and Van were meant to "be out the way and irrelevant in the grand scheme of things other then "an allegiance made from throwing them in the mud together!" Instead it turned around in the worse way (especially for Aria's father, at best Aria's LOYALITY to her home, NOT HIM means that the King CUTTING UP his territory WON'T be as HORRIBLE as it's going to be anyway LOL, but to be SAVED by "The useless one" who was using something "made by what was suppose to be her EQUALLY USELESS Betrothed" yeah that's going to FUCKING Sting...especially the USELESS BETROTHED THAT'S GOING TO GET MUCH OF HIS LAND AS A REWARD ALONG WITH A PROMOTION! Putting him in a FAR WEAKER position as said "Useless one's Future Father in Law!"
Van's Dad's only positive is that he IS acknowledging that the time of ELEMENTAL Supremacy is coming to an end, not BECOMING WEAK as he showed in the final battle once the enemy lost their RANGE edge against him. But in that "Having any of the basic Elements is an INSTANT you're meant to be strong" while having neither or any of the "unwanted" ones like Van and Arti's means you're "destined to be the load at WORST in Van's case, or can only do ONE THING in Arti's case!" (Controlling organics does come off as creepy, but with Arti's Puppet Magic, it got alot worse when a High Ranking Official was almost assassinated by a Puppet Mage, instead of just seeing the Assassin as just an Assassin, them being a Puppet Mage was used to condemn ALL PUPPET MAGES OF BEING THE SAME! Like there haven't been ELEMENTAL Assassins, but I assume because of the accomplishments of those like Lady Baroness and Van's Father, they were "given the benefit of the doubt" by the Ignorant Masses, where in the Puppet Mages have no major accomplishments so that incident made them an INFAMOUS magic type as people focused on ONE THING of the magic........and anything else was considered MUDANE or LOWLY! Like Arti's showing her mother a Puppet dancing which only REMINDED her that her daughter was a Puppet Mage for one, and for Two "she's wasting precious time she could use making herself more appealing as a Noble Woman and Bride Candidate to a good house that would OVERLOOK her DISGRACEEFUL MAGIC (Typical Older Generation ignorance that one should "Waste their time" doing something to their advantage! Ironic and funny when you call them out on THEIR Time habits in which they'll fight you to the DEATH to prove "their time wasters are indeed NOT TIME WASTERS! Damn Old Timer Hypocrisy LOL). And that's not even getting into the major part that it was an INVENTION that defeated him, NOT MAGIC! The Bombs weren't made with magic, and WORSE they were utilized by the Empire being the FIRST IN THEIR WORLD to realize what a "Bombing Run was" LOL as the Bombs did NOT lose potency by how far they were dropped, at best if one exploded before reaching the bottom, oh well the bomber had ALOT of bombs to drop to their luxry....something Van went "Hahaha NO!" with the LONG RANGE Balistia! The Empire made the First Bombing Run in their world......and Van made the first EFFECTIVE Anti Air Deterrent in their world (Only way to harm Wyvern Riders is if they get close, now with Van's "Turrents" they can fire at further range, making being a Wyvern Rider THAT MUCH MORE DANGEROUS)
There's irony in how Van and Arti's were major contributors to defeating the Occupying Forces using Production and Puppet Magic.......and the Occupying Forces, THEN "Invading Forces" used BOMBS, which could be produced AND Puppet Mages riding out of magic range with Dragons controlled with Puppet Magic. Hell the Biggest Danger during the Invasion to take back the Fortress city was an EARTH DRAGON controlled with Puppet Magic that had a "FUCK YOU I'm a Firing my LAZER" Heat Beam that had a HUGE Radius AND Reach Range when fired, that's an "all they wrote folks" for anyone in front of the damn thing when he fires! The Mistake he made, well EVERYONE in the Kingdom made was that they assumed the Imperial's were going to STICK to one strategy, when it's clear they were ALWAYS aiming for an invasion, at best the King and PM underestimated the TIMING. Discovering later AFTER THE FACT that the Empire's "Peaceful negotiations" were essentially a Distraction from the Invasion, the dependance too much on the Marquis (Van's Dad) success in pushing them back all the time was the Folly, cause they assumed he'd ALWAYS succeed, the irony is if not for his (The King's) Curiosity (And dragging his entourage of knights, the PM and his son the Crown Prince with him to Van's territory), and Van in General, the Invasion Force would have been unnoticed till they took over the March before anyone in central noticed the Invasion force Occupied a now WEAK POINT on their flank! His dad LOST the battle to prevent the Fortress City from being Occupied, and note what would happen to the Civilians if Van and the King's forces hadn't made it there in time or at all if Van wasn't well VAN as the Invasion force WANTED to make sure the spread of information that they occupied the March's Major Fortress City had to be as LESS SPREAD as possible (Of course that was MOOT with the King there, but the Invasion force never expected ANY of the shit to fall apart, majorly starting with Van, and the secondary being the King merely wanting to meet Van put him WITHIN the March RIGHT as their invasion happened, This can be BAD for the Empire if it tries to FEIGN IGNORANCE since the King fucking WITNESS and even fought their invasion force with at least some of their PRINCES the Emperor
s sons commanding the forces, so they can't play "Mere Organized Bandits who HAPPEN to have War Assets like Wyverns and shit' that and TWO Imperial Princes taken captive.) This is a HUGE Blunder for them when the King brings them to task for the invasion as War was NOT declared. But without the factors, I doubt Van's father could have turned things around and take his March back......he'd have likely died in the attempt to retake the City (as there would NOT be backup from the King who was there already AND ESPECIALLY Van's forces who majorly CARRIED the Siege) and he'd likely get wiped out by the Bomb run they were about to do on him
