Yes, that is Takeru.
Played it, TDA was fucking great! The animation, the final battle scene, everything. It was so well animated to the point where it was comparable to a anime.
The other side story was very misleading (Oh age). Comedy, Flirting, Ecchi, etc. It was so funny.

However, their is a major plot hole. In the end of TDA, you see Takeru, with long hair, looking all depressed and shit, dressed as a imperial guard. However, it brings to question why does the Takeru in Alternative not have any memories of this, when TDA blatantly takes place in Unlimited? It was heavily implied that the TSF at the end of Unlimited was Takeru, however this was completely blown off the theory.
Also, Sagiri is with the French. He also looks purple and baby faced as ever. Fuck Sagiri, causing problems for Japan in Unlimited and Alternative alike.
The major problem with Chronicles is that it is too short. In this case, it's as if they sacrificed quantity for quality, which is good, but they may have tipped it over a bit too much. I finished the VN in 5 hours.
