Virgo and his group, whom Tsugikuni Yoriichi had dispatched to Fish-Man Island, were also successfully sent off by Kuma. Yoriichi could hardly be said to trust Virgo, which was precisely why he had placed others in Virgo's team.
Of Smoker and Kujaku, Yoriichi actually only knew Smoker's background. Kujaku was Tsuru's granddaughter and had always been well protected by Tsuru. Back when Yoriichi was at Marine Headquarters, he had never even heard of her.
Although he did not know her identity, Yoriichi knew that the three of them had come to Whole Cake Island together back then. Kujaku's background was likely far more complicated than what his investigation had uncovered.
Having Smoker and Kujaku carry out the mission alongside Virgo was also meant to keep Virgo in check. Although they were all spies from Marineford's side, Smoker and the others did not know that Virgo had once been a pirate!
Before Smoker and Kujaku, Virgo would not—and would not dare to—give himself away.
As for Aramaki...
Among the rookies of their class, the one Yoriichi thought most highly of was actually Aramaki, who had eaten the Mori Mori no Mi.
The boy's worldview, shaped by his upbringing, was not exactly what Yoriichi would call upright. But Aramaki was highly malleable. He held a heartfelt admiration for the New Marines and for Tsugikuni Yoriichi.

For some unknown reason, Fish-Man Island
