Tenma had a feeling Viti was downplaying some aspect of this task if he was using words like that. His face paled immediately when the other boy confirmed what the samples actually were. Downplayed indeed.

He tried not to look as green as possible as Viti explained the process, his mind trying desperately to replace the idea of him prodding human flesh with something else.

"O--Okay..." He coughed, barely stable on his feet.
