"The answer is... agreement." The Synthetic Human from the Nestor Research Department took out a stack of documents from the storage compartment in its chest and handed them to them.
All seven of the deceased had criminal records, having spent time in Nestor Prison, with the longest stay being 1 year and the shortest at 3 months. Five of them had signed an agreement to voluntarily donate their bodies to the Nestor Corporation Research Department for disposal after death. In return, the Research Department would give them some living funds, take care of their families, and improve their lives in prison, finding ways to get them released early.
"These are the five... What about the other two?" Saiguchi Ryuuken asked with a solemn expression.
"We've talked to their families, and they agreed to donate," the Synthetic Human from the Research Department took out two purchase orders, both with legitimate electronic signatures.
