Weiß Kreuz was one of the anime I watched in childhood, and although it's not as good as I had remembered when I rewatched it, it's still a good watch. I never watched the OVA as well as the follow up anime, so I went ahead doing that.
As for this OVA, it's horrible. It's screaming plot holes even for someone like me who is not nitpicking everything just to find a plot hole which is not actually a plot hole.
Anyway, the anime ended with Aya-chan, Ran's sister (the guy who took the alias Aya), waking up and Sakura telling her about him. Unfortunately, there was no mention of Aya-chan and Sakura in this OVA. (Not even in the first two episodes of Weiß Kreuz Glühen, which I've watched so far as of today, 3rd of March 2024.) It is to be expected that the Weiß quartet would survive, but there being no mention of these girls seems strange. I had to think that the Weiß Kreuz I watched in this OVA is perhaps from a different dimension because their actions here are not consistent with the tv series.
The art style is worse here.
**SPOILER TERRITORY**
Unbeknownst to them, Kritiker was held hostage and they were given a false mission. We learn later that they suspected and knew about it, but it boggles my mind how they acted like they killed each other. In fairness, there was some emotional realism displayed by Omi that it is futile for them to fight and kill each other. Okay, so far, so good.
But the reveal that they were just acting and deceived their enemies seem hard to believe. They thrusted their weapons to each other. How were they able to come back as though nothing had happened, and in full health defeat the enemy? No matter how I try to suspend my disbelief, I just can't regarding this clusterfuck.
