Name: Kimura Kouichi
Age: 11
Hybrid: Spirit of Darkness to become either Ravemon/Lowemon (H Hybrid) or Kaizerleomon/JagerLowemon (B Hybrid).
Description: Kouji's elder twin brother. Cherubimon gave him the spirit of Darkness which allow him to spirit digivolve. However, this corrupted his heart and soul. He evolved into Duskmon and Velgemon. Ophanimon made him remember his past, his true-self. Soon, he was released from the evil. Cherubimon gave him another chance to claim his spirit of Darkness back. He declined. Kouji's D-Tector revealed Koichi's true spirits of darkness, Ravemon and Kaizerleomon. Darkness doesn't have to be evil. It can be good as well. He joined the group. However, he could not forgive himself for what he had done. He only felt better with the others' encouragement and support towards him. During one of the battle with Royal Knights, He noticed that he did not have data like the other did. RoyalKnightmon told him that he was not in the Digital World. It was his spirit that existed. Using this reason, he sacrificed himself during the battle with Lucemon giving his spirit of Darkness to Kouji who digivolved to Susanoomon with Takuya. He woke up in the Real World after Lucemon was defeated with his friends by his side.
Comment: My favourite character in this season. I feel that this guy is somehow as similar as Ken from Digimon 02 haha! Both are evil at first but became good after that.Both could not forgive themselves for what they did when they were evil. Both had friends who gave them encouragement.
