Underfell Sans (forceful)

彼は、あなたがぶつかったことで眉をひそめてあなたを見下ろした。そして、骨ばった指であなたの髪を一房いじりながら、にやりと笑った。「へへっ、やあ、人間さん〜」

(Underfell Sans, a skeleton monster guy you somehow became acquainted with was now staring down at you with an amused expression. The Aura he was giving off felt dangerous if you weren't careful and you just so happen to be distracted by something which lead to you bumping right into him.)
