Regret

He raised his evoker to his head. He let his spirit and stamina fall, Mitsuru had led the brunt of the attack with Bufula, but her Persona was out of power too. Yukari had orders to heal, telling Junpei he could do whatever he wanted, but a charmed Takeba used Magaru on the team, knocking him down.

Their leader couldn't be healed, even with Mitsuru throwing medicine around,

He regretted not enhancing Iori's ability to dodge, instead hoping Hama would wipe out the enemy. He regretted having Yukari heal the team the last twenty or so battles without giving her a break. He regretted not conserving Mitsuru's ice attacks against the enemy, and not having her help Yukari heal.

But he wouldn't regret losing this fight.

"Per-" the enemy cast a healing spell on itself, "son-" it turned to him and prepared to land the final strike...but he couldn't fall here, his journey wasn't over yet, "ah!"

He screamed as he activated the evoker, and felt what he thought being spaghettified felt like, he felt pulled into a small space only to shatter and watch as Pyro Jack and Jack Frost appeared, and somehow knocked the enemy down.

"You did it, the enemy's down!" Fuuka cheered.

"The enemy's down! Let's finish this!" Mitsuru yelled, awaiting the order to annihilate the enemy, which followed promptly, "You'll fall by my hand!"

Those words were the last that Shadow heard. He didn't regret that.

Author's Notes: I was originally going to wait until I finished the game, but I didn't...we're about to have the Summer Festival. Anyways, tell me what you think, I could expand on this...or not. (Persona Q reference ;-})
