keiko has been with Yusuke since they were children she's smart although her slaps are deadly she's always putting Yusuke in his place she nags at him about school Keiko was the one who brought Yusuke back from the dead by kissing him giving her life energy she was kidnapped by Hiei during the spirit break in and almost turned into a demon after Keiko was running for her life with Botan who was trying to keep her alive for Suzaku was trying to kill her in order to make Yusuke suffer she watched Yusuke during the dark tournament fighting for his his friends lives her and Botan become good friends she lives with her parents Keiko doesn't learn about Yusuke being a spirit detective until during the Sensei saga she loves Yusuke more then anything during the three years Yusuke was gone Keiko missed him so much when Yusuke returned Keiko and Yusuke ended up getting married and running Keiko's parents resturant.

Koenma is ruler of Spirit world his father is King Enma Koenma runs spirit world he's smart wise he met Yusuke when Yusuke died he's Yusuke boss from Spirit world during the dark tournament after Genkai died by muscles Koenma had to take over as the fifth member in order for then to compete in the semi finals against the Toguro team Koenma went against Sensei who tried to stop him then after Sensei went through  the portal along with Hiei Kurama Kuwabara his father King Enma ordered out Yusuke's termination Koenma wouldn't let his father's army kill Yusuke the army tried to hurt Koenma Yusuke heard everything and was resurrected and tried to get the army to fear him but it was only a joke they hopped on Puu and went into the portal to stop Sensei which Yusuke did after Koenma told Yusuke to becareful for his father was still after him at the end Koenma along with Botan returned to Spirit World to continue there work.

Botan is the Grim Reaper she funny bubble head air head kind of a ditz she took Yusuke to meet Koenma she is his assistent and she helps out she's very happy unless something bad happen then she is sad she doesn't like to take friends to spirit world since she death and collects souls to be taken to spirit world during the dark tournament she had to take Genkai spirit to spirit world after she died by muscles during the Sensei Saga she had to report to Koenma about what was happening after Koenma went to find Yusuke Botan found Keiko who was worried about Yusuke they ran for the world was in chaos when Yusuke died Keiko had Puu he died but came back to life when Yusuke was resurrected at the end she stays in spirit world with Koenma and still ferries souls to spirit world she sort of has a love thing for Koenma.

Kuwabara's older sister she also has spirit awareness like her brother although she's more aware then her younger brother she can't make a weapon out of it like her brother can she's always smoking ciggerettes and yelling at her younger brother during the dark tournment she felt alot of spirit awareness especially durning Hiei's fight with Bui she then watched her little brother be killed by Muscles which was heartbreaking for her after during the Sensei she helped Keiko and Botan find shelter they ended up near a large whole that Was created by Sensei Shizuru lives with her brother and still rags on him for being an idoit but she only does it because she loves her brother and tries to be there for him when he needs guidence.
