If I may! A plot spoiler for the veeeeery end of E15:
I also agreed with Titania on this point, and refused to battle him, even though it was kind of a damn tough choice. But I will vouch for the other side and say Taka's in... a pretty tough spot. There's two likely outcomes of him running from his position as a Meteor Admin:
1. Solaris hunts him down. Literally. He's shown no qualms about murdering multiple people on multiple occasions, but since Taka is his son, he might not try to kill him. At the very least, though, there would be (probably really intense) repercussions for not doing his job AND embarrassing Solaris as a high-ranking member. This, however, is proooobably not the most likely of the two consequences, as having Solaris out of commission to hunt down his son is probably not an option at that point.
2. Taka is replaced by someone far less sympathetic like, say, Sirius. Without Taka, it wouldn't have been possible to progress and save Titania at the same time, and Amaria would either have been killed, or have succumbed to her wounds, if not held as another bargaining chip. Not to mention Taka letting you out of the cage if you refuse to fuel Fern's ego. So by removing Taka, that removes a huge asset for the protagonist. But, uh, this puts Taka at more emotional and physical risk, since it seems like the Meteor members are at least aware of his shenanigans.
Wonderful outcomes for a stressful situation! But yeah, it's a shame you don't have time to have a looooong discussion with Taka. Dude needs a hug!
