Promises to protect everyone.
95% of the time it's Hikarichan.
Regardless if it's going back to the Digital World Solo.
Or being with her as she battles her demons or is possessed.
Or jumps off a dam cliff just seeing an image of her with no way knowing if he would be ok or not.
It doesn't matter. If his Hikarichan is in danger then he will go to any length to save her. Not even common sense will stop his determination.
Not his family. Not Patamon. Not any evil Digimon. Not the other Digidestined. Not even any worlds that threaten to separate them.
He knows the weight of his choices. You can feel him protecting her when she turns her head his way as if just him being there makes everything a little better.
If you see him like that all holy judgment will be unleashed with righteous fury.
And of course he'll show up clutch like he always does to show how much he cares. His track record is crazy.
Shout out to Digimon archive btw.
