NanaRikoReg

NanaRikoReg is the friendship between Nanachi, Riko, and Reg from the Made in Abyss fandom.

Canon
Nanachi, Riko and Reg are close friends in the series. Riko and Reg have met before meeting Nanachi, however the both of them treat Nanachi as close companion. Riko and Reg give Nanachi a reason to live after Mitty passes away, and they later joins them on their adventure down the abyss. They all support each other, and care for each other deeply.

Riko is very important in Nanachi's ability to open up with the both of them. When Nanachi actually meets Riko, she has been poisoned, and is experiencing the effects of the abyss. Due to these complications, she is on the verge of death. Reg begs for Nanachi's help, and they agree. Riko does end up making a full recovery, and sees Nanachi as not only an ally, but also as a dear friend. Riko also cooks for Nanachi and teaches her how to cook throught the series. Along with cooking meals, she is also very affectionate with Nanachi. Riko often hugs Nanachi and cuddles them.

As mentioned previously, they are all very close with each other. Reg is also important to Nanachi, but in a different way then Riko. Reg is less touchy compared to Riko, however this is because Nanachi says his hugs are 'too lewd'. Despite this weird aspect of their friendship, Reg becomes very protective of Nanachi like he is with Riko. Reg even puts Mitty out of her misery as a favor to Nanachi. Because of this noble dead, they become closer. When the gang goes down to the 4th layer, Reg is horrified to know that Bondrewd is not only the reason why Nanachi is not human, but is also the indirect cause of Mitty's death. Later, Reg ends up defeating Bondrewd out of a fit of rage.
