After joining the Gaku Ka unit, Riku Sen's achievements in the battlefield over the years earned him the rank of lieutenant in Mou Ten's independent unit.
Sanyou Aftermath Edit
After the Sanyou Campaign, he lead some unit members to push the Wei back into the mountains. Upon his return, Rikusen informed Mou Ten that the Hi Shin Unit had been on a losing streak in their recent battles. Telling Mou Ten of the Hi Shin unit's failure at Bijin Bridge, both him and Mou Ten were shocked to see Mou Ki who should have been on route to meet Shin.
Coalition Invasion Edit
During the skirmish with Haku Rei , Mou Ten used Rikusen as a distraction to strike Haku Rei.
Riku Sen is strong enough to be entrusted with leading a squad in the Gaku Ka unit. Being a lieutenant indicates that he has some leadership skills as well. Also, he is confident enough to take part in reckless missions during the combat.
