The hope had been that this dragoon, like Tyr, would be willing to leave Daiki alone so that the magic of the dragon armour could be preserved instead of being lost because of all the ones possessing it being trapped inside these ruins. Or rather, sealed away for so long that for them to be released was no longer a possibility. If that had been the case this wouldn't have been a problem. The man could just have observed the event and let them leave afterwards. That was most certainly that the half dragon had been hoping for, since this man gave the impression that he would most certainly be a difficult opponent to fight.
However this was not to be, as it looked like whoever this man used to be, he didn't approve of the current state of things at all. Instead of being willing to at least talk or give them a warning he just charged at Daiki immediately, fast enough that he would most likely just trample her without ever slowing down. He certainly had the size, the mass, and the strength for such a thing, and since Daiki was putting all her focus in attempting to learn the dragoon magic as quickly as possible she was in no position to try and dodge, making her a very valid target. Normally such a tactic wouldn't work at all: being large, strong and heavy would usually mean that you would be dodged fairly often, and your hopes would be pinned on getting at least one hit in. It was only because the man's target was somebody who wouldn't budge even when he was charging her that he now posed a serious threat, a lot more than if he was more like Tyr.
Fortunately enough Tyr at least managed to get in between the dragoon and Daiki, deflecting him even though it was obvious to the half dragon sticking to the shadows that doing so was not something she could keep doing. The other dragoon was simply too much of an unstoppable force for somebody like Tyr, who clearly was more balanced when it came to speed and strength, to keep holding him off when he could just keep charging like that. They would have to do something more permanent to restrain this opponent. The problem being that he was completely clad in that armour and he looked like if they tried to bind him he would just rip off those bindings and keep charging. Like a wild rhino who had chosen its target and would gorge it on its horn no matter what might be in its way. Honestly Akeya found these kind of opponents both dumb and annoying. Normally they were just dumb because she herself was nearly impossible to catch for somebody like this dragoon. Annoying because usually they weren't targeting Akeya herself but somebody or something she had to protect, which meant that her own ability to evade and dodge meant very little. If she evaded he would just charge straight through towards his actual target.
Still, that didn't mean that Akeya was useless in this fight, as she would show this dragoon. While Tyr once again deflected the man Akeya moved forwards, looking like a shadow herself as she approached the man straight from behind. She wasn't so stupid that she would just linger there and watch the fight when it was so obvious that Tyr couldn't handle this on her own. The man looked completely focused on reaching Daiki, and by extension focused on getting rid of Tyr because she was in the way and was actually showing enough strength to not be trampled by him. On the other hand that meant that he wasn't in a position where he could afford to suddenly turn around and deal with the half dragon coming up from behind. Well, technically he could do that, but he looked like the stubborn type, who would keep charging and only paying attention to those things in its path.
That belief was partially shattered when the man used the tail of his armour to grab Tyr and throw her towards the shadows, aimed precisely at where Akeya had been. However that was only partially, since Akeya had already moved, and when this half dragon of shadows and darkness moved, she moved fast. In as much time as it would take somebody to blink she had moved from her original position to right behind the man, who was still in the middle of swinging Tyr at this point. This man was very tough and very strong. That could most certainly not be denied. He would be a very tough opponent for a lot of people, purely because he could just keep charging and get rid of nearly anything that might get in his path. However that didn't take away the fact that he wouldn't be able to keep up with somebody who specialized in physical prowess without all the excessive bulk and mass. Somebody who in fact possessed the raw physical strength of dragons without needing such heavy armour to support themselves. Akeya's overall form didn't look any bigger or bulkier than that of a human female her height, but that was only a deception: Akeya's raw physical strength was not something to sneeze at, even for monsters like this guy. And unlike him she could also use that strength in her legs to move really, really fast. Even more so because she could enhance and increase her speed using shadows and magic, something which she had plenty of practice with.
Standing behind the dragoon Akeya acted fast. Tyr had been busy blocking the man's charge because otherwise he would have trampled Daiki. But at the moment that he had to stop to throw Tyr with his tail he was standing still, which was the perfect time for Akeya to act. Moving as fast as she could, to make sure he had as little time as possible to react, Akeya's own tail wrapped around the dragoon's legs, after which she spun around and threw him straight into one of the nearby ruins. He was strong, sure, and he was heavy, sure. However an important thing about strength is that just being strong doesn't in any way protect you against being lifted and thrown. You could try to lift the other person instead normally, but Akeya had attacked at a time when the dragoon was in a bad position to react. As for his weight, normally that would have been plenty to keep him securely tied to the ground. However as somebody who used that dragon armour to gain powers similar to those of a real dragon he should understand: dragons and their descendants possess terrifying physical strength.
