The Riddle Solver Who Won't Solve Riddles (ナゾカケ)

Doushite anata wa anata jishin ga kizutsuku koto de

Dareka wo mamorou to itsumo kangaete shimau no?
Hajime kara watashi ni mekakushi shita no wa anata ne?
WAIN GURASU wa, hontou wa futatsu atta no deshou?

Kare wa "doku" de shinazu to mo
Izure "NAIFU" de shinde ita no yo

...Anata no kawari ni NAZO toite agemashou
Konna katachi de jiken wo owarase wa shinai
Sabitsuita noroi wo toite agemashou
Ijiwaru na hannin ga kaketa noroi wo

Katarareta koto ni uso ga atta to shika omoenai
Ano jiken no toki, anata wa hontou ni "tantei" datta?
Mou subete kako ni owatta koto da to iu no nara
Doushite anata ga sonna ni aseru hitsuyou ga aru no?

Karera wa hitori to futari shika
Korosezu hannin ni wa narenakatta

...Sono mimimoto de sasayaite agemashou
Anata wo machigaete koroshite shimau mae ni
Watashi ga anata wo NAZO toite agemashou
"Gokuaku na hannin wa anata de wa nai"

Watashi wo tasuketa sono ude ga
PIANO wo hiku tame ni aru to shitte ita nara
Watashi wa ubawazu ni irareta no kashira...

...Watashi ga, futatabi NAZO kakete agemashou
Kono NAZO wo toite shimau hito ga arawareru nara
Kono monogatari ni tojikomete shimaimashou

"Youkoso, watashitachi dake no sekai e"
