Cause its late at night here so I try with the given characters that you have placed already first. I'll try more the next morning to give a more detailed report.

Firstly, I would like to know what is the MVP ranking. How is it being judged and calculated? How does it compare to anything?

2ndly, I would like to know what is the remaining hp of pests per turn. Giving the amount of dmg of each girls to the pests does not give much help because the pests can die by any turn which I have no idea of. I believe for the graphs, the x-axis is the number of turns but there are no labeling for this. I suggest adding the numbers for the graphs will be a huge help as the abilities of some girls are activated by the 3rd turn which may changed the battle quite drastically. This will definitely help the player a lot in many ways in planning and knowing the value of the said girl.

Furthermore, I realised the total amount of damage that the team makes is more than the total HP of the boss and the pest. It does not make any use to us to know anything beyond the turns when all the pests have died. In addition, maybe you should add an option to edit a Pest Number 3 since commonly 3 enemies rather than just one.

That's all for now. I'll make an even more detailed report the next day. I have to add though, this is a nice idea. I like it only a bit but there's still some things that's clearly and have no time for me to mention at the moment that need to work out.
