"Pulsar" is NOT a specific star system, that's translated a bit wrong.
A Pulsar is a star type, specifically a subtype of Neutron Stars.
It's "A Pulsar system" not "The pulsar system". They don't know where exactly the enemy is right now.
Thanks for the multiple chapter release. Ah, this arc. IIRC it's one of my favorite because the number of battles in it. Can't wait for the next chapters.
I am so looking forward to the next couple arcs. I read the novel, but I really prefer having a visual medium to see the content rather than just imagining it.
