Well upon using a technique I created that Saito knows named Secret Technique: Enhanced Cellular Revitalization this made him immortal, and yes i do know it requires the user life but if the user is immortal then they would be able to use this technique without dying themselves. As for Saito he could have earned the trust of Chiyo and proved to her that it would be used for a noble cause like she intended it to be.
