I really love Sensei's work. The way he tells a story through facial expressions is just the best! Here's hoping he'll do some more. Maybe we'll get lucky and he'll do a full comic some day.
This one features the word gattai, which is basically the sound that giant anime robots make when they combine, unite, dock (whatever you want to call it). I thought that whole dialog was pretty fun. I could see someone taking this in a number of fun directions next: Let me unite with you too Mom! Don't worry honey, it's not a gangbang, we're just making a giant robot and Mom is the body, so all these guys are just gonna plug in wherever they can. Uh oh, it looks like Mom is over heating, we better cool her down with this white fluid from our groin firehoses!
