Hot Blood (1x6)

:

Just before Jun Zaizen's surgery, his blood is lost in an accident during transport. Jun's blood type is rare, occurring in only one in 10,000 people. By coincidence, Ken has the same blood type as him, so he volunteers to donate blood. Commander Daigo warns that donating blood could be life-threatening for Ken, who is a cyborg. However, Ken decides to donate blood for Jun's sake.
