The newly formed second division is getting ready for the next mission in Kyoto. The aim is to prevent the Time Reversal Army from interfering in the upcoming historical events surrounding the Teradaya Incident. However, the increasingly powerful opponents can only be defeated if the swords act as a unit in human form. This is exactly where the plan seems to fail, because Kunihiro suddenly seems to show his true face. Only Kanesada can stop him, but the internal conflict puts him in a quandary even more than anyone else. After Mutsunokami already had to meet his former champion, Kanesada and Kunihiro will finally face this fate. The outcome of the decisive battle will not only influence the course of history, but also the future of the Touken Danshi.
