Kisuke Urahara vs. Reigai-Kisuke Urahara

Kisuke Urahara vs. Reigai-Kisuke Urahara is the conflict between Kisuke Urahara and his Reigai counterpart as Urahara and Kon make their way to Kagerōza Inaba's hidden second laboratory by the Senkaimon in Seireitei in order to restore Ichigo Kurosaki's reishi in the form of a Mod Soul.

Prologue
After Urahara finished up his infiltration into the S.R.D.I. as part of his investigation of Kagerōza Inaba and the Twelfth Division, he makes a quick check on the records of each Division's recruits and discharges between his exile and Inaba's first appearance at a library. He and Kon then head to the 10th Division. As they evade Shinigami patrols, Urahara reminds Kon about Nozomi's and Inaba's differing accounts of their origins. He explains about his theory on the two's accounts both being correct by the possibility that Inaba is also a Mod Soul. This would mean that they were both once part of another Mod Soul. Urahara then poses the question on who made the Mod Soul that Inaba and Nozomi came from. Urahara surmises that the two must both be Mod Souls based on the true Mod Soul developer since Mod Souls are originally created from the Reishi of a Shinigami and then enhanced. Thus, Nozomi and Inaba are both the first Mod Soul and the Mod Soul developer. He tells Kon that by finding this developer, they will likely find the laboratory as well. He states that he had been investigating this theory by searching for evidence of a Shinigami who disappeared prior to Inaba's arrival, but the 12th Division records had been erased and in the library, he found evidence of the information in the 10th Division's records from ninety-six years ago being altered. Upon making further investigation of the unaltered records at the Tenth Division's barracks, Urahara finds the record of Ōko Yushima and concludes from the record that he is in the Nest of Maggots. As they go through the Nest of Maggots, the two encounter Reigai-Suì-Fēng and Reigai-Marechiyo Ōmaeda. The two are able to get past them as Urahara defeats the two with Benihime's abilities. However, they are surprised upon finding that Yushima is in a comatose state. The two seem to be at a dead end, but Urahara had suspected this might happen upon finding Yushima. He then finds a clue to the lab in the form of a small trace of blood on the floor left from an injured Inaba. While unable to detect Inaba's reiatsu, Urahara is able to to use his reishi-collector to trace the Thought Inhibitor Drug Mayuri Kurotsuchi implanted in Inaba in an earlier encounter to pinpoint Inaba, who must be located at his true laboratory. The two then make their way to the Seireitei's Senkaimon, where Inaba's laboratory is located at. Before they can go any further, they notice a Reigai version of Urahara standing guard. He tells Kon that this certainly is the correct place and that he will have to fight his Reigai double. He instructs Kon to find a way in when he throws the first attack. Kon expresses his doubts as he does not really know what to do and is not particularly skilled with machines. Urahara assures Kon that the process is identical to what he did at the S.R.D.I and that he will follow to him as soon as he can. He tells the Mod Soul to do what he can until then. However, Kon still feels very nervous until Urahara renews Kon's determination by telling him that Nozomi should also be there. Urahara notes the entrance's location to Kon, and the two set their plan into action.
