Prior to the Battle Edit
During the Battle Edit
During their run, Itsuki kept grazing his car on the guardrails due to inexperience in mountain racing. After a few corners, Shingo taps Itsuki resulting to both being injured while crashing.
After the Battle Edit
While Itsuki is being hospitalised, Saori leaves Itsuki due to bad memories. ￼This infuriated Takumi and vowed revenge despite Iketani and Kenji heeding him with warnings of Shingo's method of a gumtape deathmatch.
