|Japanese name:||道 蓮|
Ren tries hard to maintain a tough and confident exterior and is aloof, but deep down would risk his life for his allies. Ren is a particularly impatient person with a very short temper, and isn't afraid to hurt the source of the anger.
Ren is an egotistical person and usually doesn't care that people think that he's overly proud. He even named his own team, Team "The Ren", much to the annoyance of his teammate, Horohoro. His overflowing self-confidence annoys some of the other characters. In addition, Ren is also very intuitive, quick-witted, and sometimes stubborn. He is also very defiant. He rarely listens to what anyone says or takes their instructions. Before and during the process in which he befriended Asakura Yoh, he even was bold enough to disobey his father on various occasions.
As the Shaman Fight progresses, Ren begins to trust others more. Out of all his friends, his bonds with Yoh and Horohoro seem to be the strongest. Ren often fights with Horohoro and the two do not seem to get along at all. However, after Ren is fatally stabbed by Peyote Diaz, it becomes apparent that they really do care for one another.
