@LoweGear: Getting sent to the hospital due to friendly fire is something Tais would like to avoid. Friendly fire is good though cos his primary job is to test the effectiveness of his device and getting blasted often means more chances for Yui to gain data. She would prefer to get data under less embarrassing situations though.
If he gets constantly sent to the hospital, it means his device isn't working as intended. Basically he's one unlucky lab rat
@An Hero in Disguise: Precisely. In order to get into combat (real actual combat), he needs a serious buff. He's not meant to go onto the front lines, he's just suppose to be a lab rat.
@Kha: I counted only 4 pink lolis, so who's the fifth? Also, with what I'm planning only Fate besides the 5 lolis might get involve.
PS: It would be very useful if Tais gets attacked more often (better chance of getting a buff), so I'm declaring open season on Tais and feel free to blast him when his E.V.A device is activated.
PPS: Use less extreme spells please, I still need him alive and intact.
