8 Dir Billboard Update

I have come back for help. How do I make a 8 directional sprite rotate?

I'm trying to make my own system that is animated with Unity's animation tools and doesn't require SignedAngle. The script I have is this.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class DirectionalSprite : MonoBehaviour
6. {
7.     public int directionInt;
8.     public float charRot;
9.  
10.     public float playerAngle;
11.     Vector2 cameraToSprite;
12.     Transform playCamera;
13.     Vector3 direction;
14.     float angle;
15.     public float monAngle;
16.  
17.     public DemonScript demon;
18.  
19.     void Awake()
20.     {
21.         playCamera = GameObject.FindWithTag("MainCamera").transform;
22.     }
23.  
24.     // Update is called once per frame
25.     void Update()
26.     {
27.         monAngle = transform.rotation.y * 1;
28.         direction = playCamera.transform.position - transform.position;
29.         playerAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg;
30.         playerAngle += charRot;
31.  
32.         if (charRot > 180)
33.         {
34.             charRot = 0;
35.         }
36.  
37.         if (charRot < 0)
38.         {
39.             charRot = 180;
40.         }
41.  
42.  
43.         if (playerAngle >= 0f && playerAngle < 45f)
44.         {
45.             directionInt = 0;
46.         }
47.         else if (playerAngle >= 45f && playerAngle < 90f)
48.         {
49.             directionInt = 1;
50.         }
51.         else if (playerAngle >= 90f && playerAngle < 135f)
52.         {
53.             directionInt = 2;
54.         }
55.         else if (playerAngle >= 135f && playerAngle < 180f)
56.         {
57.             directionInt = 3;
58.         }
59.         else if (playerAngle >= -180f && playerAngle < -135f)
60.         {
61.             directionInt = 4;
62.         }
63.         else if (playerAngle >= -135f && playerAngle < -90f)
64.         {
65.             directionInt = 5;
66.         }
67.         else if (playerAngle >= -90f && playerAngle < -45f)
68.         {
69.             directionInt = 6;
70.         }
71.         else if (playerAngle >= -45f && playerAngle < 0f)
72.         {
73.             directionInt = 7;
74.         }
75.  
76.         demon.SetDirection(directionInt);
77.     }
78. }

Based of my first attempt at 8 dir sprites. But the problem I'm encountering is how to rotate the character. Any help to give?
