The Nara listened carefully to the man's words, curios to know more about the situation in Irkalla. If the man's words were truthful, the situation seemed to be more dire than expected. The Nara had questions, one's that he himself would need to figure out.
Before he could respond to the mans question a set of people arrived, if you can call them all that. It was a mix of beasts and humans, a familiar face and some loud characters. It was quite convenient that the Inuzuka made an appearance, especially given the topic Horus had brought up. It had been some time since they last saw each other, but the last vivid recollection Shirou had was of the time the Inuzuka recovered from an explosive situation...
Nodding to his clone, Shirou would leave Kotetsu and the questioning to him. Shirou himself would respond to Horus' invitation.
Investigating this Fox seems like a wise choice for the moment. Based on Kōtetsu's word, we should be able to navigate rather peacefully. The Nara contemplated how the rift will function. While he trusted what the Inuzuka was saying, there was a lot more to discover regarding the actual mechanics.
Shirou would head towards the rift entrance while his clone stood behind the Inuzuka and the man, awaiting their hushed convo to conclude before approaching them.
Horus moved towards the man with the white hair, close enough that only they would hear his words as he spoke of what he found in the other rift (Hiruko rift). With that he would enter the rift, hoping his two new team mates would follow suit.
